What happens to your photo, in order
- Rotation — the frame is tilted slightly before anything else happens
- Optics — simulates what a real lens does: soft focus, camera shake blur, edge distortion, and corner darkening
- Film emulsion — adds light bloom and halation (the warm glow that bleeds around bright areas)
- Chemistry — applies the film's tonal character: contrast curve, colour response, highlight clipping
- Grain — added last, on top of everything, sharp and never smoothed out
Black & white conversion
When converting to mono, the engine weighs the colour channels the way Kodak Tri-X film does — slightly favouring reds, then greens, then blues.
Optical accidents
Base frames are pin-sharp. Imperfections are probabilistic — each one has a chance of firing on any given shot:
| Effect | Chance | Intensity |
|---|---|---|
| Corner darkening | 70% | mild always, heavy sometimes |
| Bloom | 40% | subtle always, strong sometimes |
| Camera shake | 15% | slight always, pronounced sometimes |
| Frame tilt | 15% | barely-there always, noticeable sometimes |
| Halation glow | 15% | faint always, vivid sometimes |
| Edge smear | 15% | slight always, strong sometimes |
| Focus miss | 15% | off by default, soft when active |
Film character guarantee
Every frame is checked for three qualities: grain presence, movement, and contrast. If none are showing, one is quietly raised to a noticeable level. If only one is present, there is a 75% chance a second joins it. This ensures no frame ever comes out looking like a clean digital photo.
