Features

Everything in the toolkit.

One app, organised by the thing you actually do: capture, look, grade, finish. Below is the full set of tools Acetate ships with.

Pure RAW capture

Shoot ProRAW. No baked-in processing.

Acetate writes the sensor's full uncompressed data — Apple ProRAW DNG — straight to your library. Every stop of dynamic range is preserved for the edit. Standard iPhone JPEGs throw away the highlight latitude and crush the shadow detail; Acetate refuses to.

  • ProRAW (DNG) on every supported iPhone
  • Full sensor dynamic range, no flatten
  • EXIF preserved through capture, edit, and save

Pro shooting modes

Manual when you want it. Assisted when you don't.

Auto, Program (P), Shutter Priority (S), ISO Priority, Manual (M), Night Mode, and Long Exposure up to 30 seconds. Swap ultra-wide, wide, and telephoto with a tap. Live readouts of ISO, shutter speed, and EV compensation stay visible the whole time you're shooting.

  • Seven shooting modes covering every situation
  • Three-lens lineup with one-tap switching
  • Long Exposure up to 30 seconds for night work

Exposure tools

Nail the exposure on the first frame.

Live RGB and luminance histograms. Highlight and shadow zebras with adjustable thresholds. Full-frame false-colour exposure map. Adjustable focus peaking in your choice of colour. Dual-axis level indicator with haptic confirmation so you can keep the camera on the subject, not the screen.

  • RGB + luminance histograms, live
  • Highlight + shadow zebras with adjustable thresholds
  • False-colour exposure overlay across the full frame
  • Focus peaking + dual-axis level with haptic lock

Film looks

Eight era-grade LUTs, hand-tuned.

Skip the generic vintage filters. Acetate ships eight curated 3D LUTs covering the eras most photographers chase — '70s Warm, '80s Neon, '90s Cinema, Golden, Mono, Faded, Moody, and Cross. Press and hold any thumbnail in the camera to preview it live before you commit; tap to lock it in.

  • Eight curated 33-cube LUTs in the bundle
  • Press-and-hold to preview live in the camera
  • Per-filter intensity slider blends 0 → 100 %

Bake your own LUTs

Save any edit. Apply to anything. Shoot in it.

The killer feature. Edit a photo until you love it, hit Save as Filter, and Acetate bakes your full colour pipeline (Light, Colour, HSL, Curves, Split Toning, Grading Wheels, the active filter) into a portable .cube LUT. Apply it to other photos with one tap. Load it in the camera and shoot tomorrow's photos in the same grade.

  • Save any edit as a portable .cube file
  • Apply saved LUTs in editor AND camera
  • Import .cube files from Files, iCloud Drive, AirDrop
  • Export to share with Lightroom, Premiere, DaVinci

Three-way colour grading

The DaVinci workflow on iPhone.

Real Lift / Gamma / Gain colour wheels for Shadows, Midtones, and Highlights — the same primary correction tool every Hollywood colourist uses. Each wheel has its own luma slider. Single CIColorKernel under the hood — one GPU pass, no extra render hops, real-time preview.

  • Three wheels with draggable pucks (hue × saturation)
  • Per-range luma slider on each wheel
  • Lift / Gamma / Gain math, not triangular weights

Editing depth

Pro tools that don't muddy.

HSL runs in OkLab perceptual space, so a 20° hue shift doesn't drift saturation or luminance. RGB tone curves per channel + master. Split toning with hue/saturation/balance. Filmic highlight rolloff (Reinhard-style compression). Dehaze, texture, grain, vignette, three-stage edge-aware denoise. Real depth, no toy sliders.

  • OkLab HSL — perceptually uniform, no chroma drift
  • Master + per-channel RGB curves
  • Filmic tone mapping with shadow lift + highlight rolloff
  • Three-stage edge-aware denoise (median → CINoise → composite)

On-device intelligence

Smart tools that never leave your phone.

Scene detection optimises your photos automatically. Auto-straighten finds the horizon. Object Removal erases unwanted elements with a tap (A15 / M1 or newer). All of it runs on-device using Apple's Vision framework and on-device Core ML — no cloud round-trip, no telemetry, no upload of your photos to anyone.

  • Vision-based scene detection + auto-straighten
  • Core ML object removal with smart-crop ROI
  • Colour-matched seam blending — no visible patch
  • Works fully offline; no account required

Selective adjustments

Edit anywhere. Or just here.

Radial and linear-gradient masks let you push exposure, saturation, temperature, sharpness, and clarity on just part of the photo. Multiple masks can stack. Feather radius and invert are one tap.

  • Radial + linear-gradient mask types
  • Stackable: multiple selective adjustments per photo
  • Per-mask: exposure, brightness, contrast, sat, temp, sharp, clarity

Tactile interface

Made for the photographer's hand.

Haptic feedback for the shutter, lens-swap clicks, and the level-lock confirmation. Live readouts always visible. Composition grids, before-and-after compare, unlimited undo and redo with proper history coalescing — drag a slider and the whole drag is one undo step, not fifty.

  • Haptic feedback at every meaningful interaction
  • Composition grids + dual-axis level indicator
  • Unlimited undo / redo with drag coalescing
  • Press-and-hold anywhere to compare before / after
