Film Lab 35

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.

REAL PHOTOCHEMISTRY

Every stock is built on a 13-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. Decode back to linear light
6. Two-layer grain synthesis
7. Per-channel characteristic curves
8. Color chemistry simulation
9. Scanner simulation
10. Print stage (paper contrast and crossover)
11. Halation glow
12. Output encoding
13. Optical finish (bloom, vignette, softness)

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, saturation, and grain from clean to a pushed-negative 400 percent. The Darkroom section adds real lab controls: push and pull development, printer lights, highlight compression, and a film format dial. 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.
