ChobialHow the films are made. No filters were harmed.
A Chobial film isn't a filter laid over a finished picture. It's a recipe applied to the RAW: the light your iPhone caught, before anything was baked in.
Light first. Film second. You last.
- RAW
The sensor's data, or Apple ProRAW. Nothing is sharpened, smoothed or styled yet, so there's room to work.
- Develop
Exposure and white balance are set on the scene's own light, the way a lab sets a print, before any look goes on.
- Film
Tone curves for each channel, then colour moved hue by hue: how much each one gains or loses, and which way it turns. This is where Gold gets warm and Chrome goes quiet.
- Film physics
Grain that sits in the midtones like the real thing, halation's red glow round bright lights, and bloom.
- Your edits
Light, colour, curves and masks go on top, and every one of them can be undone. The RAW never changes.
Three roads to a film.
Matched to photographs
Most of the first 24 were matched against reference photographs and checked with a colour-difference score, ΔE, frame by frame. Low numbers mean you'd struggle to tell them apart.
Shot as camera recipes
A few, like Gold, Postcard, Expedition and Vintage, started life as camera recipes people love, shot and then rebuilt as films.
Read from datasheets
22 were modelled on what Kodak and Fujifilm published about their films: how each layer responds to light, how dense it develops, and how it prints. The simulation is spectral_film_lut by Jan Lohse (MIT licence), and each result was fitted as a film you can edit.
