WHAT IT IS

Not another filter app.

Film Lab 35 is a physically-informed simulation of real film photochemistry. Every stock profile was built from analyzing over 1,500 real film scans, measuring shadow color, highlight rolloff, grain texture, and color temperature across every exposure condition.

The result: photos that feel like film, not like a preset.

01 · THE STOCKS

Twelve iconic film stocks.

Portra, Tri-X, CineStill 800T, Velvia, Ektar, HP5 Plus, Polaroid, Instax, and more. Each one tuned against real scans, not aesthetic guesses.

02 · THE RITUAL

Watch your photo develop.

Every frame passes through a ten-stage rendering pipeline. No instant filters. A tactile, intentional experience that honors the craft.

03 · THE SCIENCE

Physics, not presets.

Linearization, log exposure, Hurter-Driffield density curves, emulsion cross-talk, scanner simulation. The full darkroom in code.

04 · YOUR PRIVACY

Everything stays on your device.

No cloud processing. No tracking. No accounts. Your photos never leave your phone.
