Film Lab 35 is a darkroom in your pocket. This is not a filter app, this is a physically-informed simulation of real film photochemistry, built from analyzing over 1,500 real film scans. Select a film stock. Watch your photo develop. Save your frame to your own local Lightbox. 12 ICONIC FILM STOCKS Color Negative - Kodak Portra 400 - The gold standard for portraits - Kodak Gold 200 - Warm, nostalgic, everyday magic - Kodak Ektar 100 - Vivid saturation, fine grain - Fujifilm 400 - Clean, cool, natural - Fujifilm disposable 400 - That summer camera look Slide Film - Fujichrome Velvia 50 - Landscape legend, electric greens and blues Tungsten / Cinema - CineStill 800T - Signature red halation, tungsten balance Black and White - Kodak Tri-X 400 - Iconic punchy contrast - Ilford HP5 Plus - Soft, nuanced, open shadows Instant - Polaroid 600 - Warm, faded, dreamy - Fujifilm Instax Mini - Clean instant snapshots Experimental - LomoChrome Metropolis - Desaturated, moody, cinematic REAL PHOTOCHEMISTRY Every stock is built on a 10-stage rendering pipeline that simulates actual film behavior: 1. Linearization of your input 2. Log exposure mapping 3. Film density curve (Hurter-Driffield) 4. Emulsion layer cross-talk 5. Per-channel characteristic curves 6. Color chemistry simulation 7. Two-layer grain synthesis 8. Halation glow 9. Scanner simulation 10. Final compositing Learn more about the process in the in app Science tab. THE DEVELOPING RITUAL Watch your photo develop through every stage. No instant filters. A tactile, intentional experience that honors the craft. DATA-DRIVEN AUTHENTICITY Each stock profile was developed by analyzing over 1,500 real film photographs where we measured shadow color, highlight behavior, saturation, contrast, grain texture, and color temperature across multiple exposure conditions. Every parameter is informed by real measurements, not aesthetic guesses. ALL LOCAL, ALL PRIVATE Your photos never leave your device. No cloud processing, no data collection, no tracking. Everything runs on-device. No cloud, ever. GENTLE POST-PROCESSING Once your photo is developed, optional fine-tuning lets you adjust brightness, contrast, warmth, and saturation. These adjustments sit on top of the "photochemical" render and they don't break the emulation. YOUR LIGHTBOX Every developed frame is saved to your personal local Lightbox: a collage of your film work, arranged like prints on a table. WHAT YOU GET FREE Start with three iconic stocks: - Kodak Gold 200 (warm everyday) - Kodak Tri-X 400 (classic B&W) - Fujifilm Disposable 400 (summer vibes) Unlock individual stocks for $0.99 each, or get all 12 plus future additions with the Full Lab bundle.

Our emulations are original artistic interpretations.
