Acetate

iPhone / Photo et vidéo

The Digital Darkroom for Purists.

Acetate bridges the gap between pure RAW capture and the soul of analog
film. Built for photographers who understand that an image is made, not
taken — every adjustment runs on-device, no cloud, no account, no tracking.

PURE RAW CAPTURE
Shoot in Apple ProRAW (DNG) on every supported iPhone. Acetate bypasses
standard processing and writes the sensor's uncompressed data straight to
your library, preserving every stop of dynamic range for post.

PRO SHOOTING MODES
Full manual or assisted: 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.

CINEMATIC FILM LOOKS
Eight curated 3D LUTs covering the eras most photographers chase —
'70s Warm, '80s Neon, '90s Cinema, Golden, Mono, Faded, Moody, Cross.
Press and hold to preview live before you commit.

BAKE YOUR OWN LUTs
Save any edit you make as a portable .cube LUT and apply it to other
photos with one tap — or load it in the camera and shoot in your own
signature look. Import any .cube file from Files, iCloud, AirDrop, or
third-party providers. Export to share with Lightroom, Premiere, DaVinci.

THE EDITOR
Full-strength tools designed for image-makers:
• Three-way colour grading wheels (Shadows / Midtones / Highlights) with
per-range luma — the DaVinci Resolve workflow on iPhone
• OkLab perceptual-space HSL for hue, saturation, and luminance shifts
that don't muddy or clip
• RGB tone curves, split toning, filmic highlight rolloff
• Dehaze, texture, three-stage edge-aware denoise
• Radial and linear-gradient selective masks
• Mood presets — eight curated cinematic looks with intensity control

ON-DEVICE INTELLIGENCE
Smart tools that run entirely on your iPhone using Apple's Vision
framework and on-device Core ML:
• Scene detection optimises your photos automatically
• Auto-straighten finds the horizon for you
• Object Removal erases unwanted elements with a tap (A15 / M1 or newer)

PRO EXPOSURE TOOLS
Live RGB and luminance histograms, highlight and shadow zebras, false-
colour exposure map, customisable focus peaking, dual-axis level
indicator with haptic confirmation.

TACTILE INTERFACE
Haptic feedback for the shutter, dials, and level lock. Live readouts of
ISO, shutter speed, and exposure compensation are always on. Composition
grids, before-and-after compare, unlimited undo and redo.

PRIVACY FOCUSED
Your photos are yours. No account, no cloud, no analytics. Location is
used strictly for EXIF geotagging on photos you take, and never leaves
your device. The entire app — capture, edit, AI, save — works offline.

Don't just filter. Develop.
