Crazy Film: Negative Converter
Light meter & film scanner
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Now on iPad. The grading suite is rebuilt for the big screen: curves and HSL side by side, larger colour wheels, and type that's finally easy to read.
Crazy Film — a film camera in your pocket. From light metering and shot logging to development timing, and on to negative copying, conversion and pro color grading, it covers the entire analog workflow. Everything is processed on your device — no internet, no uploads.
Pro Light Meter
· Real-time metering with aperture / shutter suggestions based on your film stock and scene
· Face-priority exposure: automatically detects faces and meters for them; pick which face when several are found
· Spot / average / Zone System metering modes
· Rangefinder: precise LiDAR distance measurement, with a dual-camera estimate as a fallback on devices without LiDAR
· Depth of field / hyperfocal: real-time ranging shows the depth-of-field range and hyperfocal focus point at a glance
· Focal-length equivalence, exposure compensation, reciprocity correction, color-temperature meter and illuminance reference
Shot Log
· Record aperture, shutter, EI, lens, GPS coordinates & place name, and notes — for every roll and every frame
· Auto-writes EXIF and links to your gear library, so your work is fully documented
Development Timer
· Built-in reference recipes for black & white and color (C-41 / E-6 / ECN-2)
· Multi-step timing + agitation reminders + a loud alert at each step; live progress on the Lock Screen / Dynamic Island
· Temperature compensation, push/pull conversion, kit-capacity and reuse-time compensation
· Times are for reference only — always follow the official instructions for your chemicals / kit
Negative Conversion · Pro Grading
· One-tap negative-to-positive from a copy shot, for both color and black & white
· Soft highlight recovery and shadow color-cast removal: highlights no longer clip to pure white, deep shadows no longer turn blue-purple, blacks stay clean
· Curves, HSL, color wheels (shadows / midtones / highlights) and LUT grading
· Multiple reveal animations (peel-apart, blinds and more); the default "Instant" shows the finished photo right away
· Dust removal and lossless export
3D Film Album
· A self-contained library with photos shown as 3D cards you flip through like real film
· Spatial display: with a virtual backdrop on, photos appear right in front of you, Vision Pro–style
Live Conversion Preview
· Point at a negative on a lightbox and watch positive colors appear instantly as you compose
Privacy First

Ratings & Reviews
Native iPad support
Crazy Film is now a real iPad app, not a stretched phone layout. Every panel has been rearranged for the larger screen.
· Rebuilt grading suite — Curves and HSL now sit side by side, so there's no more switching back and forth. The curve is square with the channel buttons stacked along its edge, which makes control points far easier to drag. Colour wheels are bigger, with the RGB readouts moved out to the sides. · Larger type throughout — Interface text has been stepped up across the app, and it now follows your system Text Size setting. Parameter names, preset names and tab labels are all clearer. · Roomier panels — Export, frames, film-strip splitting, recipes and every other screen now open at a larger size on iPad, so there's far less scrolling. · Better strip splitting — Buttons, sliders and preview thumbnails are all larger, making offset and frame spacing much easier to fine-tune.
Other improvements
· Terms of Service and Privacy Policy now open full screen instead of resizing mid-load. · Avatar, handwritten signature and brand logo now use the in-app photo browser, which is faster and more reliable. · Fixed a number of text sizes that were too small to read comfortably.
