1.5.1 Latest 6 August 2026

A fix for Quick Export in the Library.

Fixed

  • Quick Export follows your selection in the Library. Pick a photo in the Library, press Quick Export, and it exports that photo. Chromogen opens your selection first if it isn’t already the one you’re editing, so the export is always of the picture you chose — its image and its file name.

Good to know

  • Everywhere else Quick Export is unchanged, and nothing about how a photograph develops or exports has changed. Your photos, edits and settings are untouched.
1.5.0 6 August 2026

Text on your photographs, designed for you.

New

  • The text composer. Write a headline, a subhead and a few lines of body, and Chromogen designs the layout over your photograph — where the words sit, how large, in what order of importance, in a colour that stays readable, with a matched pair of typefaces. Try another look gives you a genuinely different arrangement each time you press it.
  • Choose the type, or let Chromogen choose. Set a font for each role — headline, subhead, body, label — or leave it on Automatic. The typefaces that come with Chromogen travel with your edit and render the same on Windows and Mac; your own installed fonts are there too, listed under “This PC”.
  • A tool bar that becomes a text editor. Press T and the bar over your photo turns into type controls — font, weight, size, colour, effects, italic, caps, alignment and justified — and Photo tools turns it back. It follows the bar wherever you dock it, along the top or down a side.
  • Find a font by typing. Open any font list and start typing; it narrows to what you mean as you go.
  • Weights that are really there. Bold is one click, and the caret beside it opens the full range a typeface actually ships — Light through Black. A typeface with no bold of its own says so rather than faking one.
  • Type on the picture. Double-click any text to edit it where it sits; click a selected piece again to deselect it.

Improved

  • Designing is immediate. The first design, each new look, and switching fonts all happen without waiting — including deep into a long run of Try another look.
  • The photo gets the room. Opening Text folds the navigation to a slim icon rail and gives the width to your picture and the tool bar; leaving restores it. Your own choice about the rail always wins.
  • The Curves editor shows its grid again, in both the light and the dark interface.
  • Before / after tags know when to step aside. Slide the divider all the way across and the tag for the half you can no longer see gets out of the way.
  • Shorter, clearer hover tips across the app, plus a new Show tips under controls switch in Settings › Appearance for the small grey lines beneath controls.
  • In Masking, the small labels under Subject, Object, Brush, Gradient, Radial and Luma read in full instead of cutting off.

Good to know

  • Text you have already placed is untouched. Existing designs render exactly as they did before, pixel for pixel — and nothing about how a photograph develops or exports has changed.
1.2.9 6 August 2026

Write on your photos — the new Text workspace.

New

  • The Text workspace. Write a headline, subhead and body and Chromogen designs the layout over your photo — automatic font pairing (or choose your own families), composition looks from quiet to hero, over the photo or as a poster, all on a measured grid. Try another look explores a genuinely different arrangement every time.
  • Edit type right on the picture. Double-click any text to type into it where it sits, drag it into place with grid snapping, and style it from the toolbar — font, size, italics, underline, caps, alignment, colour.
  • A text toolbar that lives where you work. It appears at your tool rail’s edge, snaps to any side of the canvas — a full row on top or bottom, a slim column on the sides — or floats wherever you drop it. Grab the grip or any empty part of the bar; the wand tries another look without opening a panel.
  • Copy and paste edits between photos. ⌘C copies the developed look, ⌘V applies it to another photo — crops, healing and text stay with the photo they belong to.
  • Save exactly the preset you mean. Tick what the preset carries — tone & white balance, colour, curves, grain, effects, detail & RAW, an imported LUT — and file it into a group as you save.
  • Panels remember how you left them. Collapsed sections persist across photos and restarts (Settings › Editing).

Improved

  • The photo gets the room in Text. Entering the Text workspace folds the navigation to a slim icon rail and gives the canvas the width back; leaving restores it. Your own collapse choice always wins.
  • A tidier frame. The collapsed navigation rail is balanced around its icons, live “On” indicators on colour and effect cards stay current as you edit, and preset previews are steadier when browsing quickly.
  • Finer control. Hue adjustments move gently near zero instead of jumping, and photos without previous edits always open clean.
  • Clearer tips. Hints across the app say what things actually do — and one switch in Settings hides them all.
1.2.8 31 July 2026

Batch editing that works, honest previews everywhere, and a library that does what you ask.

Fixed

  • Copying edits between photos actually copies them. Sync Edits in the Library silently failed on photos you’d edited before — the old edits kept winning. Copies land every time now, previously-edited photos included, and thumbnails and the big preview update the moment it happens.
  • Presets carry your whole look. Saved presets quietly dropped the Color Mixer’s “All colors” shift, Film Response and Color Grain — and applying any preset reset those three on the photo. They’re captured, applied and left alone now.
  • Saving back to Lightroom or Capture One no longer changes the picture on screen. The saved file was always correct, but the canvas re-applied your film stock on top of the already-baked image the moment the save landed. What you see now is exactly what was saved.
  • Every preview shows the real developed look. RAW thumbnails used the camera’s own punchy JPEG, so the grid disagreed with the editor — and a preview, once shown, could stay stale for the whole session. Thumbnails, the filmstrip, the photo strip and the big preview all render through the real develop pipeline now and refresh whenever edits change. First view of a RAW folder builds its previews once, then they’re instant.

New

  • Choose what to copy. Sync Edits now shows exactly what’s moving — from which photo, onto which photos — with ten tick-boxes (film stock, preset, RAW develop, lens, tone, white balance, color, curves, effects, local adjustments). Crops, healing and text never copy — they belong to one photo. The highlighted photo is the source; copying a RAW’s look onto a JPEG translates it so it matches.
  • The library does more from a right-click. Remove any folder — parents included — from the library (files stay on disk, and it stays removed). Send a photo to a moodboard without leaving the library, or jump straight into Develop.
  • Scrolling can’t nudge your sliders. Two-finger scrolling over the panels only ever scrolls them now. If you liked adjusting sliders with the wheel, turn it back on in Settings › Editing.

Improved

  • Selection you can read at a glance. Selection rings sit just outside the photo with a breathing gap — never covering your pixels — in the library, the filmstrip and the Film Stock browser, and the photo that’s open in the editor wears a small EDITING tag.
1.2.7 30 July 2026

Masks stay where you put them, the crop tool behaves, and the assistant actually understands you.

Fixed

  • Masks follow the crop on RAW files. Creating a Subject, brush or gradient mask after cropping a RAW aimed it at the original framing instead of your crop — and masks made before cropping drifted off when the crop landed. Both orders are correct now: every mask stays glued to the part of the photo it was drawn on, through crops, rotation and straightening. JPEGs were never affected.
  • The crop tool no longer strands your photo. Opening the crop tool could leave the picture parked high with a large empty area below it, especially after a second crop. The crop view now always fits and centres, a stray two-finger scroll can’t shove it, and the photo strip steps aside so the frame gets the full canvas.
  • The brush lets go. The paint brush had no way out except switching tools — Esc now ends it, and so does picking or adding any other kind of mask.
  • Questions stop editing your photo. Asking the assistant “why is exposure 1?” used to set exposure to 1. Questions are answered now, never applied.
  • “Don’t add grain” no longer adds grain. Negatives are understood: “no grain” clears it, “don’t make it warmer” returns to the as-shot white balance.

New

  • Enter applies the crop, Esc cancels it — the shortcuts you already have in your fingers.
  • The assistant understands far more. Typos just work (“wamer”, “grian 30”). Intensity registers — “super warm” leans twice as far as “warmer”, “slightly” goes gently. Complaints work the way you’d say them: “too warm” cools it, “not warm enough” warms it, “too much grain” dials grain back. And plain description works: “less warm”, “more grainy”, “softer”.
  • Masking waits for the crop. Adding a mask while the crop tool is still open used to place it wrongly; it now asks you to finish the crop first, so you never get a silently mis-aimed mask.

Improved

  • The ⌘K assistant bar is real frosted glass — it genuinely blurs the photo behind it instead of just being see-through, so the text stays readable over busy images. It also floats above the photo strip now instead of closing it.
1.2.6 30 July 2026

The external-drive fix: photos on USB and Thunderbolt drives open properly again.

Fixed

  • Photos on external drives open correctly now. Opening a photo from a USB or Thunderbolt drive could show a black screen, with Develop reporting “volume isn’t responding” even though the drive was healthy — most often during or right after a big import. The app was treating every external drive with the caution reserved for network shares; local drives are now read directly, like the internal disk.
  • Faster opens off external drives. The same change removes a behind-the-scenes copy step for every photo on an external drive — opens read straight from the drive now.
  • Honest messages. If macOS is blocking access to a drive (System Settings › Privacy & Security › Files and Folders), Chromogen now says so and points at the setting instead of blaming the drive. Network drives keep their protective behaviour, and “reconnect the drive” is reserved for drives that are genuinely unreachable.
1.2.5 29 July 2026

Retouching grows up: heal spots become layers you can manage — and exports are now pixel-faithful to the canvas.

New

  • The Retouch panel. Your heal repairs now live in the Masking workspace as proper layers: every pass shows its spots, and each row has an eye to mute it, a trash to delete it, a Strength dial to fade the whole layer, and double-click to rename. Fix dust and New pass moved in beside them, and clicking New pass now shows the waiting layer immediately.
  • Fresh sessions. Coming back to a photo you retouched before starts a new cleanup layer automatically, so today’s work never mixes into last week’s.
  • An eye for the overlay. Press O (or the eye on the heal bar) to hide the spot outlines while you judge the result — the repairs stay on.

Fixed

  • Healing on RAW files is fast now. The tool was re-copying the full-resolution image on every frame while a repair existed; it reuses it now, so brushing and sliders stay smooth on big files.
  • Exports match the canvas. Exactly. An export now binds to the frame you accepted — if you click Export while an edit is still rendering, it waits for that exact result instead of racing it, and changing output settings afterwards can’t affect a queued export. Every exported file also carries an explicit sRGB tag so Preview, Photos and browsers all agree on its colour.
  • Preview grain matches export grain. The canvas used to render grain slightly weaker than the exported file at the default quality; what you see is now what you get.
  • The “Exporting…” status can no longer get stuck if a photo reload is interrupted mid-export.

Improved

  • The heal cursor and spot outlines are clean black & white — no more amber tint sitting over the very skin tones you’re trying to judge. Selection reads by weight: the active repair is the bright, thick ring.
  • The heal bar matches the app — same chrome as the crop bar, and it now sits clear of the filmstrip instead of covering it.
  • The ⌘K assistant bar is properly glassy and no longer lands on top of the Photos pill.
1.2.4 28 July 2026

A fast fix for Film Stock previews — plus an assistant that now works without any setup.

Fixed

  • Film Stock previews behave now. Cards no longer flash, go stale, or show the previous photo’s look while you browse, hover, or switch photos rapidly — the preview pipeline was rebuilt with pooled renders and hard fences at photo boundaries. If you saw wrong-looking stock cards in 1.2.3, this is the fix.
  • The window buttons stopped sulking. The traffic lights kept their colour rules straight through Settings, minimize and full screen — and no more “double dots”.

New

  • The assistant works offline now. Press ⌘K and just type: “warmer”, “grain 30”, “push 1”, “shot exposure -1” — every develop slider responds. Ask “where’s vignette?” and it takes you there; ask “what does push pull do?” and it knows. No account, no key, nothing leaves your Mac. (Connecting a provider is still there for open-ended edits.)

Improved

  • Truer highlights on clipped suns. The RAW engine’s new neutral default keeps blown highlights and sun rims honest instead of tinting them.
  • Faster photo opens carried over from the load-time work, and drag a filmstrip card onto the Reference pane to pin it.
1.2.3 28 July 2026

A reference photo beside the editor, a tool bar that docks or floats wherever you work, richer gradient masks — and your masks now travel between Windows and Mac.

New

  • Pin a reference photo beside the editor. The new Reference pane holds any photo next to the one you’re editing — drag one in from the filmstrip, from Finder, or straight off a web page (Pinterest, Google Images…). Comparing a photo with itself shows your finished look, not the flat original.
  • A tool bar that docks or floats. Dock it flat to any edge on its own lane — never over your photo — or drag it out to float anywhere. It compacts under your hand while you drag, springs onto an edge with a real glide, tucks into a little puck on a double-click, and quiets down when idle (you choose how much, in Settings).
  • Gradient masks grew up. A master Amount for any mask, both-ways gradients with independent per-side handles (fade tighter above than below, or the reverse), one-key Invert (X) and overlay preview (O), arrow-key nudging, and proper move / rotate cursors on the guides.
  • Your masks now cross between Windows and Mac. Gradient, zone and radial masks — and AI-raster brushes — made on one platform now open on the other. Mac edits keep every Windows brush recipe intact for the trip back. (Hand-painted stroke brushes still render on Windows only — they’re next.)

Improved

  • It feels faster everywhere. Photos open quicker, sliders stay sharp while you drag them on typical photos instead of dropping to a blur, film grain previews render several times faster, and the compare view opens and closes smoothly.
  • Small polish: the Reference tool wears its own icon now, and dragging a photo out of the filmstrip just works — drop it on the reference pane.

Fixed

  • Compare mode lag is gone — opening, closing, and docking the tool bar during compare are all on one smooth clock, and closing with two RAWs open no longer stalls.
  • Comparing a photo with itself looked different from the editor — the reference now mirrors the editor’s exact rendering.
  • The tool bar minded its manners: no more covering the photo when docked, colliding with the filmstrip tray, or oversized cursors on the gradient guides.
1.2.2 26 July 2026

Chromogen is now native on Apple Silicon — plus a big round of stability and polish.

New

  • Native on Apple Silicon. A dedicated M1–M4 build — no more Rosetta translation. RAW decodes and exports run on your Mac’s own architecture, verified pixel-identical to the Intel build. Intel Macs keep their own build; the download page now offers both.
  • Cull with Picks and Rejects. In the Library, P picks, X rejects, U clears — each auto-advances to the next photo. Rejects fade back, a new Flag filter shows Any / Picks / Rejects, and flags follow photos through renames and moves. A reject never touches the file.
  • Collections. Albums that reference your photos instead of moving them. Right-click any photo → Collections. Adding, removing, even deleting a whole collection never touches a file on disk.
  • Press ? for the keyboard cheat-sheet, and I in the photo preview for an info card: camera, exposure, size, and your marks.
  • Rotate from the crop corners. Grab just outside any corner of the crop box and turn to level the horizon — a proper rotate cursor shows the way, and the straighten dial follows along. The crop controls now appear where your tool bar is, instead of hiding at the bottom of the window.

Fixed

  • The app no longer freezes while editing photos on an external drive. If your drive or network share fell asleep mid-session, saving could stall. A sleeping drive now costs one brief pause at worst, and your edits are always kept in memory.
  • Cropping a RAW no longer washes out your edits. Applying a crop (or rotating, or straightening) silently switched off the RAW develop — the photo looked reset, and exports of cropped RAWs were washed out too. Every format we support was verified pixel-identical before and after cropping.
  • Crop behaves like a proper tool now. The photo re-centres after you apply; dragging the box back out to the full frame actually removes the crop; Cancel rolls back everything the session changed — including corner rotation; and Reset Edits works in one press.
  • Tools let go when you’re done with them. The colour and white-balance pickers can be put away (Esc, or just pick another tool), the curve’s Pull from photo stops following you across workspaces, and the masking brush’s Erase actually erases — including the promised ⌥-to-erase.
  • “Pull from photo” now shows its state honestly — a bright pill while armed, quiet while not — and stays wired even after collapsing and re-opening panels.
  • Full screen (F11) rebuilt. No more flicker or low-res frames, Esc works immediately, it opens on the monitor the app is on, and closing it can’t crash the app.
  • Honest errors. A photo Chromogen lacks permission to read now says so and points at System Settings — it used to claim your camera was unsupported.

Improved

  • Faster, smoother feel. One motion system across the app, ⌘1–9 workspace shortcuts, dark tooltips everywhere, a quieter status bar, and the histogram no longer turns comb-like on round-trip files. Corner rotation previews at drag speed and sharpens on release.
  • “Reset all color” is a real button now, top-right of the Color panel — it was hidden until you hovered it.
1.2.1 24 July 2026

Richer highlights on every RAW, instant opens for the newest cameras, and a right-click menu in the photo tray.

New

  • Right-click any photo in the tray. The bottom photo tray now has the same menu as the Library: reveal the file in Finder, rename it, remove it from your library, or move it to the Trash. Remove from Library is new in both places — it clears a photo out of Chromogen and leaves the file untouched on disk.
  • The newest cameras open instantly. A RAW from a camera Chromogen can’t yet decode directly used to wait on Adobe’s DNG Converter before anything appeared — up to half a minute on a big file. It now opens straight away from the camera’s own preview and prepares the full 16-bit version in the background, so your next open of that photo is full quality. If a camera can’t be converted at all, Chromogen now says so instead of promising something it can’t deliver.

Improved

  • Brighter, more natural RAW rendering. The way RAW photos land their brightest tones has been rebuilt: highlights ease toward white the way film does, and the overall rendering is noticeably brighter, with more life in the midtones. This changes how every RAW photo looks when you first open it. Edits you have already saved are unaffected.
  • Film grain that behaves like film. Colour grain now makes a visible, film-like difference. Grain size also re-forms the grain pattern as you change it, instead of magnifying one fixed pattern from the corner of the frame.

Fixed

  • Renaming a photo no longer moves it to the end of the filmstrip — it keeps its place.
  • Clearer licence messages. If there is ever a problem with your licence, Chromogen explains what happened instead of leaving you to guess — and keeps every one of your edits saved.
1.2.0 23 July 2026

A Capture One round-trip, 16-bit TIFF support, and much faster RAW opens.

New

  • Works with Capture One. Send a photo from Capture One’s Edit With, develop it in Chromogen, then press Save — your edit is written straight back into the file, and Capture One picks up the change. The Save button even names where it will go.
  • Opens 16-bit TIFFs. High-bit TIFFs from Capture One, Lightroom or Photoshop now open in full quality — and push exposure or shadows as hard as you like without banding.

Improved

  • Much faster RAW opens. RAW now decodes across all your Mac’s cores, and several photos can decode at once — so opening a photo, and the sharpening that follows, is dramatically quicker. Big files gain the most; a 60-megapixel file’s full-quality decode dropped from several seconds to around two.
  • Natural highlights. The RAW develop now rolls the brightest tones off smoothly instead of clipping them to flat white.
  • Faster on relaunch. Library thumbnails you’ve seen before come back instantly from a cache instead of being decoded again.

Fixed

  • The Dehaze slider no longer flashes the image while you drag it.
  • Clicking a photo right after launch no longer occasionally did nothing.
  • A cleaner Heal tool icon.
1.1.2 22 July 2026

Select your subject in one click, richer grain by default, and faster RAW opens.

New

  • AI masking. Two Auto-select cards now lead the Masking picker. Subject lifts the person or object out of the frame in one click. Object arms click-to-mask — click anything in the photo and it joins the mask, named for what it found. Everything runs on your Mac; nothing is uploaded.
  • Realistic grain, on by default. New edits now start with Film Response enabled — grain that follows real colour-negative behaviour, coarsening in the shadows and sitting differently in each channel. Edits you have already saved keep exactly the look they had.
  • A persistent update banner. When a new version is available, a banner now waits in the top bar until you use it or dismiss it, instead of a message that disappeared after a few seconds.

Improved

  • Faster RAW opens. Unnecessary work was taken out of the open path. Typical RAWs open around a quarter to a third faster.
  • The Grain card, reorganised. Grain controls are grouped into Amount, Shape and Character, so the ones that change the look sit together.
  • Film stock past 100%. Stock Amount now goes to 150% when you want to push a look harder — matching the Windows app.
  • A calmer Library. Dragging the thumbnail-size slider now resizes the grid as you drag instead of rebuilding it, and the Scopes window stops working while it is minimised.

Fixed

  • Switches that stuck. Clicking directly on a toggle could flip it twice and leave it looking stuck. Toggles now flip once, wherever you click the row.
  • Toggle states in dark mode. On and off were hard to tell apart at a glance; on now reads clearly bright against off.
  • Buttons keep their own colour on hover instead of being repainted by the system theme.
1.1.1 21 July 2026

Previews that show your finished look, true-to-export colour, and a faster, steadier darkroom.

New

  • Previews you can trust. Library tiles, the photo tray and film-stock cards now show the finished look — your film stock, edits, crop and rotation — instead of the camera's own preview. Edit away and the tray thumbnail follows along live.
  • Faster hands. Double-click the photo to zoom in and back out, scroll to pan (hold ⌥ to zoom), hold Space to peek at the original, and ⌘, opens Settings — the conventions your other tools taught you.

Improved

  • RAW switching, rebuilt for speed. Flipping back to a photo you already opened is instant, first opens show an honest development sooner, and very large files develop in two stages so the canvas never sits empty.
  • Photos on network drives. A slow or frozen network share can no longer freeze the app. Originals are staged to a local cache, a stalled share affects only that one photo, and everything else keeps moving.
  • The filmstrip stays put. Photos keep their order while you edit, when you switch, and across restarts — and Library ▸ Group ▸ Date now uses the day you shot the photo, not the day you imported it.

Fixed

  • The canvas now matches your exports. On wide-gamut Mac displays the canvas rendered slightly more saturated than the exported file — what you see is now what you get.
  • Canon colour restored. CR3s from certain bodies opened washed-out with lifted, magenta-tinted blacks. The correct rendering is back.
  • Rapid switching between different RAW makes could stick on the previous photo — switching is now latest-wins, and your click always outranks background work.
  • Smaller fixes. ⌘Z undoes slider drags reliably, DNGs no longer open with a brief purple tint, and scrollbars stay slim instead of ballooning on hover.
1.1.0 20 July 2026

Moodboards that pull from anywhere, new-camera RAW support, and a faster darkroom.

New

  • Moodboards, fully unlocked. Drag images straight in from your browser, right-click to paste or add photos, and a new screenshot button snaps any part of your screen straight onto a board. Colour cards now show their hex value (plus an optional name), with a toggle to hide it.
  • New-camera RAW support. RAW formats Chromogen can't decode yet — Nikon High Efficiency NEFs and the newest Sony bodies — now open automatically in full 16-bit through Adobe's free DNG Converter when it's installed, or from the camera's own preview when it isn't.
  • A rebuilt Presets workspace. Import Lightroom and Capture One presets, install .cube LUTs, save and manage your own looks — matching the Windows app feature-for-feature.
  • White Balance: one-click Auto + presets. A three-state As Shot / Auto / Custom mode with six illuminant presets, on RAW and JPEG alike.
  • Colour Mixer "Pull from photo". Arm the tool, then drag up or down on the photo itself to shift the colour under the cursor.

Improved

  • RAW files open on sight. A developed preview appears in a fraction of a second — already wearing your film look — while the full 16-bit develop finishes behind it.
  • A tidier Film Stock library. Filter by All · ★ · Most used · Character, with previews that track what you actually apply.
  • A steadier canvas. The photo stays centred as you zoom out, fit accounts for the photo tray, tilted moodboard prints render with crisp smooth edges, and resizing shows proper macOS resize cursors.

Fixed

  • Sony a7R VI and a7CR files opened slowly with glitch artifacts — they now open quickly and correctly.
  • Interface fixes. Selection handles now sit on a tilted item's corners, panel text no longer clips, and the bit-depth chip truthfully reads 16-bit for RAW.
  • Security hardening under the hood.
1.0.1 15 July 2026

A clearer film-stock picker and a more polished trial.

Improved

  • A clearer Film Stock picker. Premium stocks now wear a PRO badge over a dimmed preview, and Nocta 500T is featured as the popular pick — so what's included, and what the full version adds, reads at a glance.
  • A more consistent trial. Once the trial ends, the darkroom reads as "look, don't touch" throughout, with clearer wording on what unlocking gets you.

Fixed

  • Licensing fixes under the hood.
1.0.0 14 July 2026

Chromogen comes to the Mac — the whole darkroom, now native on macOS.

New

  • Chromogen is now on macOS. The complete app runs natively on macOS 11 and later, on both Apple Silicon and Intel: RAW developing on the full 16-bit file, the shelf of film stocks with physics-modeled grain and halation, the zone-system darkroom, masking, multi-photo layouts, text, and clean exports. One license works on either platform, on one computer at a time.
  • Local adjustments, fully loaded. Every mask carries a complete set of local controls — Exposure, Contrast, Highlights, Shadows, Whites, Blacks, Temperature, Tint, Saturation and Vibrance — so you can dodge, burn, and grade any part of the frame, not just the whole photo.
  • True white balance on RAW. Set colour temperature in real Kelvin and tint, anchored to how the shot was taken — the absolute white-balance controls a colourist expects.
  • Your details on export. Keep the camera and shooting info from the original, and stamp your copyright into JPEG and TIFF exports. Your location is never written into an export.
1.4.1 Latest 2 August 2026

Type text straight onto the photo — and a tool bar that behaves in compare mode.

New

  • Edit text where it sits. Double-click any text on your photo and a cursor appears right there, blinking, in that text’s own font, size and colour. Click to place the cursor, select, delete, retype — the words change under your hands instead of in a box off to the side. Enter finishes a heading (Shift+Enter starts a new line), Esc undoes your changes, clicking away finishes. Double-clicking an empty spot still makes a new text layer, ready to type.

Fixed

  • The tool bar gets the whole canvas in compare mode. Comparing two photos pushed the tool bar sideways into the editing half — and with the bar docked to the left edge it could end up sitting on top of the photo you were editing. It now keeps its own strip and the compare panes lay out around it, so both photos stay whole whichever edge you dock to.
  • The selection box keeps up with your text. Dragging text on the photo left its dashed box behind until you let go; box and text now travel together.
  • All four tone buttons fit. “Highlights” was cut off in the Color panel’s Apply to row. The buttons are now sized to their own words.

Your photos, edits and settings are untouched by this update, and nothing about how a photo renders has changed.

1.4.0 2 August 2026

A quieter interface, redrawn around your photo — in both themes.

The new look

  • Panels became floating sections. The sidebar, tool bar, controls panel and photo tray are now rounded panels of the same shade, resting on one calm background with real space between them. Nothing is boxed in by outlines any more — each area is defined by its own surface, so your eye goes to the photo first.
  • A colour-neutral interface. Every shade of the interface is now pure neutral grey, in the dark theme and the light one. Nothing around your photo carries a warm or cool cast, so the only colour on screen is the colour in your picture — and your read on it stays honest.
  • The light theme, rebuilt. Light mode follows the same design: one soft background, brighter floating panels, clean white cards. Controls, text fields and buttons keep a whisper of an outline so they stay easy to pick out on a bright screen.
  • A tool bar that fits its tools. Docked to any edge, the tool bar is now a compact floating bar sized to what it holds, with proper breathing room from the photo and the panels beside it.
  • Bright outlines mean one thing: selection. The photo you’re editing and the film stock you’ve chosen wear a bright ring. Ordinary buttons no longer keep a highlight after you click them, and the outline that marks your place while tabbing appears only for the keyboard.

Also better

  • Preview backgrounds behave. The White through Black backdrop choices show exactly the shade you pick in either theme, and they colour only the area around your photo — the rest of the app stays as it was.
  • Dragging the panel edge resizes it live. The controls panel follows your hand as you drag, with no placeholder bar and no highlight running down the seam.
  • A calmer photo tray and scope. The tray opens and closes without the thumbnails shifting, its search and filter are easier to see, and the histogram sits in a clean frame that a bright highlight peak can’t cut through.
  • Preview quality is now Speed, Balanced and Quality, and it lives in Settings › Editing. Exports have always used full quality and still do, whichever you pick.
  • Toggles, sliders and colour wheels are clearer to read, properly spaced, and consistent across every panel.

Your photos, edits and settings are untouched by this update, and nothing about how a photo renders has changed.

1.3.1 1 August 2026

Copying edits now copies everything, and the Library is cleaner to look at and faster to work in.

Copying edits

  • Sync Edits carries everything. The RAW develop settings, lens corrections and borders now copy along with the rest — tick what you want in the Sync Edits dialog and the copies match the source.
  • RAW to JPEG copies match. Copying from a RAW onto a JPEG translates exposure and tone onto the sliders a JPEG actually uses, so a mixed batch comes out looking consistent.
  • The dialog says what it does. It names the open photo it copies from — the tile marked OPEN — and the ticked photos it copies onto, and the Library refreshes the moment you apply.

Library

  • The selection box sits around the outside of each photo with a little breathing room — never over your picture, polaroid-framed photos included — and photos float cleanly on the workspace background.
  • More in the right-click menu. Edit in Develop opens a photo straight into the editor. Send to Moodboard drops photos onto your board without leaving the app. Remove from Library now works on any folder — parent folders included — and never touches the files on your computer.
  • No more flash of the previous photo. Opening a photo into the editor shows the right picture from the first moment.
  • RAW thumbnails reflect their exposure edits without you opening the photo first.

Editing

  • Two-finger scrolling no longer nudges sliders by accident. Scrolling always scrolls the panel now. If you liked adjusting sliders with the wheel, turn it back on in Settings › Editing.
  • The assistant is a proper guide. Ask it questions about the app, have it take you to any Settings page, or let it prepare a private support note that you review before anything is sent. No AI key needed.
  • Saving and restoring edits is more dependable in a few rare situations.
1.3.0 31 July 2026

Masks stay where you put them, and the assistant now works without an AI key.

Masking

  • Masks and gradients stay with their subject when you reframe. Crop, cancel a crop, reset the crop, reset all geometry, rotate in quarter turns, or drag the straighten dial: your masks move with the picture. Paint you add after a crop stays put too.
  • Masks land where you painted them on RAW photos after a crop. Cropping a RAW first and then adding a Subject or gradient mask now places the mask on the framing you can see.
  • The crop box no longer jumps off the photo after you open and close the photo tray.

Assistant

  • It works with no AI key and no internet connection. Type plain requests and it acts: adjust sliders (“warmer”, “more grain”), jump around the app (“show me settings”, “export”), ask where a control lives (“where is vibrance?”) and be taken straight to it, or ask a common question and get a real answer. Connecting your own AI provider is now only the upgrade for open-ended requests, not the price of entry. Type “connect” any time to add one.
  • It answers the common questions about using Chromogen: updates, supported formats, importing, Sync Edits, privacy and more. If it cannot answer something it points you to halide@chromogen.app instead of a dead end.
  • It follows more of the way you phrase things. “Don’t add grain” leaves grain alone. “Too warm” cools it a step. “Not warm enough” warms it. “Super warm” leans in harder, “a hair warmer” leans in less. Bare words like “grainy” are taken as instructions, a trailing number sets the amount (“warm 300”), and everyday typos still land.
  • Questions are treated as questions. Asking something like “why is exposure 1?” no longer changes the setting.
  • Say “organize by date” to open the Organize window. You still pick the destination and press the final button yourself.
  • With your own AI provider connected, it reaches further: vibrance, shot exposure, push and pull, sharpening and radius, noise reduction, clarity, dehaze, vignette and straighten.

Library and film stock

  • Film-stock previews are remembered between sessions. Revisiting a photo brings its cards straight back. In our testing a warm refill is about a third quicker on a JPEG, and switching from a RAW to a JPEG takes roughly half the time it used to.
  • PNG-heavy libraries stop rebuilding their thumbnails on every launch. PNG, GIF, WebP, AVIF and TIFF thumbnails are kept between sessions at full quality. The preview cache lives with your other app data, holds up to 2 GB, trims the oldest first, and survives moving or renaming a photo.
  • Switching photos brings the film-stock cards up straight away instead of grey placeholders, with the final versions swapping in as they finish.
  • Compare in the Library now opens the side-by-side pane you already know from the editor, and it stays in the Library when you use it from the loupe. Drag any photo from the filmstrip into the left side, press Escape to go back to one photo.

Toolbar

  • The floating toolbar can stand upright. Right-click it for Float upright (vertical). A toolbar torn off the left or right edge keeps its upright shape, and the choice is remembered.
  • You can dock it to the bottom of the window again, and the outline showing where it will land hugs the bottom edge.
  • The photo no longer shrinks and springs back while you drag the toolbar to a new edge, and docking it no longer makes the photo redraw itself.
  • Starting a toolbar drag tucks the assistant bar out of the way so the two no longer overlap.

Fixed

  • Exports and previews keep every edit when a RAW is open. With a RAW photo open, a closed JPEG’s brightness and colour-temperature work could be left out of its film-stock tile, composites, split-screen and carousel output, and batch export. All of those now carry the full edit. Your originals and your saved edits were never touched, and Chromogen refreshes the affected previews itself. If you batch-exported JPEGs while a RAW was open, export them again to pick up the missing tone and white balance.
  • Escape works with a non-English input method switched on: leaving the loupe, exiting compare, clearing a selection, cancelling a toolbar drag and backing out of a crop all respond again.
  • Under the hood: a security update to the component that reads DNG files.

Nothing about how your photos render has changed: every reference image and every film stock renders exactly the pixels it did before.

1.2.9 29 July 2026

The film stock library loads the way it should — previews arrive quickly, stay put while you browse, and settle straight away when you move between photos.

Film Stock

  • Stock previews arrive several at a time. The library renders your photo through several stocks at once instead of one after another, so the grid fills in a fraction of the time it used to.
  • Browsing the library no longer interrupts it. Running the pointer across the cards while they are still filling now brings the card you are pointing at to the front of the queue.
  • Switching photos settles in one step. The library updates to the new photo once, instead of clearing and redrawing itself several times over the seconds after a switch. Changing a setting keeps each card’s current preview on screen and replaces it as the new one is ready, rather than dropping the whole grid back to placeholders.
  • RAW files switch more smoothly. The preview image behind the card grid is prepared once per photo, which takes noticeable work off the machine at the moment you move to a new RAW.

Nothing about how a stock looks has changed: every card renders exactly the pixels it did before, and your photos, ratings and edits carry over untouched.

1.2.8 28 July 2026

Masks you can actually adjust after you place them, a noticeably faster app, and a sharper image while you work.

Masking

  • Gradient masks stay adjustable. Once you place a gradient, the guide stays live on the photo: drag the outer lines to set where the fade starts and stops, drag the middle line to rotate, and drag the diamond to move the whole thing. Hold Shift for 15° steps, or nudge with the arrow keys.
  • Two-directional gradients. Choose Both ways and the effect sits in a band through the middle of the frame, fading out to both ends — a strip of light across a scene, or warmth held through a horizon. Each side is shaped on its own.
  • Invert any mask. The new Invert switch (or the X key) flips what a mask covers, and it works the same on gradients, radial spots, brushes and brightness masks.
  • Amount. One slider scales everything inside a mask at once, so you can dial a whole local adjustment up or down without touching each control.
  • See what a mask covers. The overlay is now a translucent wash instead of a solid colour, so the photo stays visible underneath while you judge the edge. Press O to show or hide it.
  • The softness control is called Feather everywhere now, and it shapes the edge of a two-directional band too.

Speed and image quality

  • The app opens about 30% faster and uses far less memory while it runs.
  • A sharper image while you edit. Balanced and Crisp now draw the photo at your display’s full resolution as you work, so the picture no longer softens mid-adjustment. Fast stays a deliberate lower-resolution choice for when you want maximum speed. Exports have always used the full original.

RAW

  • Cleaner skies around the sun. Photos with a blown sun no longer show a faint ring where the brightest area meets the sky. The transition is smooth.
  • A more neutral starting point. RAW files now open with a truer, more neutral rendering rather than a slight built-in lift — so a RAW you opened in an earlier version will look a little different. Every slider behaves as before, your edits are all still there, and your files were never changed.

Canvas and Library

  • The toolbar can take a side. Snap it to any edge of the canvas and it becomes a full bar that the photo makes room for, instead of floating over the picture. Drag it away and it lifts back into a compact floating bar under your hand.
  • Compare, improved. The reference photo now zooms and pans on its own — scroll over it to zoom in, drag to move around, double-click to fit — so you can match detail between two shots. The toolbar stays put while you compare.
  • Library and filmstrip thumbnails match the canvas, showing the same finished look as the photo you have open.
1.2.7 26 July 2026

Straighten a photo by dragging a crop corner, plus a smoother round trip with Capture One and Lightroom.

Crop

  • Rotate from the corners. Move just outside any corner of the crop box and the pointer becomes a rotate arrow — drag to level the horizon. The photo turns under a crop box that stays put, so you never end up with empty corners. Hold Shift for fine control, and the angle lands in the straighten dial if you want to nudge it by number afterwards.
  • The canvas toolbar steps out of the way while you are cropping, and the crop bar no longer disappears when you open or close the photo tray.

Sending photos back to Capture One or Lightroom

  • The save button names its destination. When you are editing a photo sent over from Capture One or Lightroom, the button reads Save to C1 or Save to Lr — and saving brings that app back to the front, so you are never left hunting for the window you came from.
  • Chromogen appears in other apps’ Open With and Edit With lists. It now registers itself for all 34 photo formats it can open, so you can hand a photo over without hunting for the program file. Your existing file associations are left alone: nothing changes about what opens when you double-click a photo.
  • A truer histogram on handed-over photos. Photos passed in from Capture One no longer show a spiky, comb-like histogram. The readings were always correct; the drawing was misleading.

Color

  • “Reset all color” is a real button instead of faint text, so you can actually find it.
1.2.6 25 July 2026

Hold a reference photo beside the one you’re editing, plus a calmer toolbar and sidebar.

Compare

  • Hold a reference photo next to the one you’re editing. The new Compare button in the canvas toolbar splits the view: your photo stays on the right, fully editable with every slider working as normal, and a reference sits on the left. Made for matching one shot’s look to another.
  • The reference shows its real look. If the reference is one of your own photos, it appears with its own edits applied, exactly as it looks everywhere else in the app.
  • Drop in anything. Drag a photo up from the tray, drag a file in from a folder, or drag an image straight out of a browser. A new drop replaces the reference. Images from outside your library are kept separate and are never added to your photo library.
  • Right-click the reference to swap it into the editor, or clear it with the small × that appears when you hover.

Toolbar

  • Dragging the toolbar now only moves it. It can no longer minimize by accident when you push it toward an edge. To minimize it, double-click its grip (or use the right-click menu).
  • Tools are grouped more clearly: selection, picking, view, and compare each sit in their own section.

Sidebar

  • A calmer collapse. Minimizing the sidebar no longer makes the icons jump to the middle, drift, or shift again a second later. The panel slides and the icons ride with it in one motion.
  • The minimized sidebar is tighter, and no longer shows a partly cut-off companion card.

Fixed

  • Library cards no longer draw two rings around the photo you have open.
  • Pick and reject marks on a card are no longer drawn three different ways at once.
  • The heal tool’s icon now matches the Mac version.
  • The app window has rounded corners on Windows 11.
1.2.5 24 July 2026

Smoother RAW highlights, more cameras, faster opens, and real colour grain.

Your photos

  • Smoother, brighter RAW highlights. Bright highlights — skies, sunlit skin, blown suns — now land brighter and softer, with the harsh colour rings that used to appear around very bright suns gone. Skin and sky keep their true colour. This affects the starting look of RAW photos only.
  • Real colour film grain. The Colour Grain option now makes a visible, film-like difference, and dragging Grain Size or Crispness now re-forms the grain in place instead of looking like it zooms one corner of the photo.

Cameras

  • More cameras open natively, including the Sony A1 II and Hasselblad X2D II, plus fixes for the newest Sony and Canon files.
  • Brand-new camera models open too. A camera too new for the built-in decoder now opens quickly, then quietly upgrades itself to full 16-bit quality in the background, so your next open is full quality.

Faster

  • RAW photos open and cull faster. The photo you click opens first — it jumps ahead of anything loading in the background — the next photo is prepared in advance, and very large files no longer stall the rest.

Fixed

  • Dehaze no longer flashes when you let go of the slider.
  • No more “Edits restored” flicker when the app starts. The filmstrip now fills out from the photo you are on instead of from the first photo, and the app opens faster the second time because finished-look thumbnails are saved to disk.
  • The before/after compare divider now lines up with the photo split (on tall photos it used to sit off to one side).
  • Licence handling is more reliable, with clearer messages if anything is ever wrong. Every edit stays saved either way.
1.2.4 22 July 2026

Better highlights on every RAW photo, thumbnails that show your edits, and a quieter, lighter app.

Your photos

  • Highlights roll off like film. Bright areas (skies, windows, sunlit skin) now ease gently toward white instead of flattening out early, and they keep their real colour, so blown-out skin no longer picks up an orange cast. This slightly changes the starting look of every RAW photo: expect a little more room in the highlights.
  • Library and filmstrip thumbnails show your edits. An edited photo's thumbnail now previews its finished look (film stock, tone, colour) instead of the flat original, so you can see at a glance what you have already worked on.

Fixed

  • RAW photos can no longer decode incorrectly when you open one while another is still loading. Opening a photo during a background load could show it rendered wrongly. Your files were never affected. RAW loading is now strictly one at a time.
  • Switching photos no longer locks up the window. Reading a photo's lens information used to block the whole interface behind a background load.

Faster and lighter

  • Quiet when you leave it alone. Chromogen kept animating in the background while idle, using power for nothing. It now settles once the sidebar companion falls asleep.
  • Uses much less memory. Thumbnails are kept at the size they are actually shown, and the AI tools release their memory after you stop using them.
  • Faster launches. Thumbnails are remembered between sessions instead of being rebuilt from every photo each time you open the app.
1.2.3 20 July 2026

RAW photos open about three times faster, and what you see while they open is now always the real thing.

Faster

  • RAW photos open in about a second. Chromogen now develops a fast preview first and finishes full quality quietly in the background, so you can start editing right away. Exports always use full quality, automatically. (Full Res preview mode keeps loading everything up front, unchanged.)
  • More of the machine works on every open. Two heavy steps of RAW loading now use all processor cores. Same pixels, less waiting.

Fixed

  • Switching photos could briefly flash back to the previous photo. Flick between RAW files quickly, especially right after editing, and the canvas sometimes jumped: new photo, old photo, new photo again. Two separate timing bugs behind it, both fixed.
  • Photos no longer change their look while opening. Chromogen used to show the camera's own JPEG preview first, which has the camera's contrast and colour baked in, so the photo visibly shifted the moment the real develop appeared. Now the canvas only ever shows Chromogen's own rendering.
  • Blown-out white backgrounds showed blotchy colour patches. On studio shots against a bright white backdrop, faint pink and blue squares could appear across the background. It now stays clean white. Bright overcast skies benefit too.
1.2.2 17 July 2026

White balance you can set in one click, colour you can adjust by dragging on the photo itself, and a fix for Canon's newest camera.

New

  • Auto white balance. Pick Auto and Chromogen reads the photo and takes the colour cast out for you. It uses the same maths as the eyedropper, so the two always agree. If a photo has nothing neutral to work from, it tells you instead of guessing.
  • White balance presets. Daylight, Cloudy, Shade, Tungsten, Fluorescent and Flash are one click away on RAW photos, under Presets. They set a starting point, then you fine-tune with the sliders.
  • A tidier White Balance panel. Mode (As Shot, Auto or Custom), the eyedropper and Presets now sit together in one row, and the panel is a row shorter.
  • Pull colour from the photo. Turn on "Pull from photo" in the Color Editor, then drag up or down on any colour in your picture to adjust it. Chromogen works out which colour you grabbed, so you never hunt for the right band. Choose whether the drag changes Hue, Saturation or Lightness, and hold Shift for fine control.

Fixed

  • Canon EOS R6 Mark III photos opened washed out in pink and purple. These files now open with correct colour.
  • The Curves "Pull from photo" pointer. It flicked back to the normal arrow while you were dragging. Both pull tools now keep the up and down arrows for the whole drag.
1.2.1 17 July 2026

A tidy-up of the Color panel, so undoing a colour experiment takes one click instead of a hunt.

New

  • Reset all color. One click at the top of the Color panel puts the whole section back to normal: the grading wheels, Master Saturation and Vibrance, and everything in the Color Editor.
  • Every colour tool resets on its own. The Color Mixer, Hue curves, Color Unify, and Even out skin each have their own Reset, so you can undo one experiment without losing the rest of your work.

Fixed

  • The Lens hide button did nothing. It now previews the photo without lens correction, like every other hide button.
  • Consistent hide and Reset buttons. In the Color panel some hide buttons sat on individual sliders, and the Color Editor showed two of everything. Every section now has exactly one hide and one Reset, and they cover the same thing.
1.2.0 14 July 2026

A big update: retouching, smarter masking, importing your own presets, a moodboard, and a tidier film-stock picker.

New

  • Heal tool. Paint over a blemish, dust spot, or distraction and Chromogen rebuilds the area from the texture around it. It holds up under film grain, and there is a one-click "Fix dust" pass too.
  • Import your Lightroom and Capture One looks. Bring your own presets, profiles, and Capture One styles into the new Presets workspace and apply them like a film stock.
  • AI masking. Click a person or an object and Chromogen selects it for you, so you can adjust just that area. Keep clicking to add more.
  • Per-mask color and tone. Every mask now carries its own Highlights, Shadows, Whites, Blacks, Tint, and Vibrance.
  • Moodboard. A space to gather and arrange reference images while you edit.

Improved

  • Tidier Film Stock picker. The filter row is now a single clean line with a "Character" dropdown, plus a new "Most used" view that surfaces the stocks you reach for most.
  • Library. A new "Imported" view for the photos you add, and you can ask the assistant to sort your library into folders.
1.1.5 13 July 2026

Bolder film looks, a big step up in RAW highlight rendering, wider camera support, and interface polish.

New

  • Film looks can go further. The Stock Amount slider now goes up to 150%, so you can push a stock past its normal full strength for a bolder result.
  • RAW photos take the look at full strength by default. Applying a film stock to a RAW file now starts at 100% (RAW opens flat, so it wears a stronger look well); JPEGs stay at a lighter 70%. You can set both defaults in Settings, under Editing, "Default Film Look."

RAW

  • Blown-out highlights render far more naturally. Clipped suns, bright skies, and blown windows now roll off smoothly to film-like tones instead of clipping to a hard edge or a seam, and bright colored areas keep a truer, warmer color instead of being pushed to flat white.
  • White Balance is now its own card with a real temperature scale in Kelvin, opening at the photo's as-shot value.
  • Black-and-white camera RAWs open correctly. Files from monochrome cameras (such as the Ricoh GR, Leica Monochrom, and Pentax Monochrome) now open as a true black-and-white photo instead of a red-tinted one.
  • More cameras open cleanly: Panasonic S1R II, Nikon Z 8 (HE), and a Sony ARW edge fix.

Improved

  • Light theme polish. The color-balance wheels, the histogram, the clipping readout, and tooltips now all match the light interface.
  • Text tool. The compose grid, its selection, and its toggles are now clean black-and-white with clearer, easier-to-tap controls.
  • Your companion, Halide. When you send Halide for a nap he now stays asleep until you poke him, and he walks back to his spot to settle down instead of dozing off mid-stroll.
  • Tidier settings. Removed the experimental Color Engine toggles from Settings; how your photos develop is unchanged.
1.1.4 10 July 2026

Your darkroom companion comes to life, plus a faster editor and a few fixes.

New

  • Halide, your darkroom companion, has been reborn. The little hooded figure in the sidebar now moves with real character: he gathers himself before he darts, lands with weight, and shows how he feels. He's happy when you pet him, proud after an export, curious when you import photos, and gets visibly sleepy before he nods off. He blinks and looks around on his own, and his tricks were reworked so each one is something you can actually watch him do.

Faster

  • Snappier editing. Adjustments render about a third faster while you drag a slider, the app starts a little quicker, and finishing a slider drag now does a single clean render instead of two. The results are pixel-for-pixel identical, just with less waiting.

Fixes

  • The film-stock "looks" pop-out no longer sticks. Opening the alternate-looks popup and clicking a stock could occasionally leave it stuck open with stocks unswitchable. One click now closes it and applies the stock.
  • Fresh installs no longer hit a first-run error. A brand-new install with no photo library yet could show a startup error. Fixed.
  • A batch of silent startup hiccups is gone. Some internal errors during launch could make the startup preview show the wrong edits for a moment. Fixed at the source.
1.1.3 10 July 2026

A gentler Contrast control, wider file support, and easier updates.

Refinement

  • Contrast keeps detail in shadows and highlights. Turning Contrast up used to flatten the darkest and brightest parts of a photo to solid black and white very quickly, which could read as too strong. It now keeps the same punch through the midtones but eases into black and white the way film does, so texture in snow, skies, and deep shadows survives. Pure black and white are still fully reachable. Photos you previously edited with a positive Contrast will render with a little more of that detail back. The negative Contrast direction, and the Whites and Highlights controls, are unchanged.

File support

  • Opens JPEG-XL compressed DNG files. Some newer cameras, and Lightroom's "lossy DNG" option, save DNG files using JPEG-XL compression that Chromogen couldn't read before. These now open at full quality, developed the normal way, with no extra software to install.

Updates

  • Check for updates from Settings. Settings now has a "Check for updates" button that tells you whether you're on the latest version and takes you straight to the download when there's a newer one.

Fixes

  • A thin white line along the top edge of the pop-out Scopes window is gone.
  • Reliability and security hardening under the hood.
1.1.2 8 July 2026

A fix for the newest Nikon cameras.

Fixes

  • Nikon ZR photos now open correctly. In 1.1.1, some Nikon ZR RAW files could still open as coloured stripes — a specific compression pattern slipped past the safety check. Chromogen now catches it and opens the real photo, from the camera's own preview or at full 16-bit quality when Adobe's free DNG Converter is installed.
  • One-click link to the free DNG Converter. When a RAW is too new to read, the message now has a button that takes you straight to Adobe's free DNG Converter, which unlocks full-quality opening of the newest RAW files.
1.1.1 7 July 2026

Newest-camera RAW support.

What's new

  • Opens RAW files from brand-new cameras. Photos from cameras too new for the built-in RAW engine (like the Nikon ZR, and Nikon High Efficiency HE/HE* NEF files) used to fail with a confusing "out of memory" message or open as coloured noise. Chromogen now recognises when a camera is newer than its RAW engine and opens the photo from the camera's own full-size preview, so the picture appears correctly and every edit and film stock still works.
  • No more false "out of memory." A RAW that genuinely can't be read now shows a clear, honest explanation of what to do, never a misleading memory error.
  • Optional full-quality path. If Adobe's free DNG Converter is installed, the newest RAW files are converted and opened at full 16-bit quality automatically.
1.1.0 6 July 2026

The film-look release: grain, edges, and a new film-exposure control, plus a wave of interface polish.

Film rendering

  • Film grain realism. A new Film Response control drives grain that behaves like the real stock. Slide and instant film hold their grain into the highlights, colour-negative grain is finer and per-layer, and shadows pick up the coarser grain real film shows. Grain now also tracks push and pull.
  • Sharper, truer film edges. The acutance and adjacency ("Mackie line") model reproduces the real over and undershoot asymmetry of film development, so edges read as film-sharp without looking digitally over-sharpened. Pushing a stock adds its edge bite automatically.
  • Shot Exposure, a new film-exposure axis. Simulate a frame shot under or over the meter, developed normally, then scanned back. Underexposed reads faded and murky, the real thin-negative look; overexposed goes soft and pastel with clean blacks. Works per film stock and on RAW.
  • Cleaner push and pull. Pulled film no longer lifts to milky blacks, whites pin back to paper white on negative stocks (slide and instant keep their honest density), and pushed highlights keep their separation instead of clipping.

Interface

  • Colour grading wheels. Lift, Gamma, and Gain now live on colour wheels with brightness strips, replacing the flat slider block. A new option (Settings, Editing) puts red at the top of the wheels, the vectorscope layout colour-grading suites use, if that matches your muscle memory.
  • Better sliders. Wheel to nudge, hold Shift to fine-drag, click a value to type it exactly.
  • Polish throughout. App-wide dark tooltips and scrollbars, Ctrl+1 to 9 to switch workspaces, window and session persistence (reopen your last photo), loupe EXIF, smoother RAW opening, and a batch of smaller fixes.
  • Cleaner photo tray. The tray filter is now a single dropdown (All, Edited, RAW, and star ratings) instead of a row of chips, and it no longer crowds the tray controls on a narrow window.
  • Friendlier start. A redesigned first-run and trial experience, with plain-English tips on every slider and a short guided tour.

Under the hood

  • Cross-platform licensing groundwork, so one key activates either platform.
1.0.0 1 July 2026
  • The first public release. Chromogen for Windows: RAW developing, a shelf of film stocks, and the full darkroom of editing tools.
