The Kodak film format
Originally, Cineon was a digital film format introduced by Kodak in the early 1990s. The .cin file used logarithmic encoding to scan motion-picture negatives while preserving the enormous tonal range of film — the highlights, the shadows, and everything between. It became a foundation of the digital intermediate workflow and influenced the log color pipelines used in cinema today, including ACES.
The browser app
Today, Cineon is also a browser-based app at cineon.app. It carries the same idea forward: instead of faking a film look with a preset, it physically simulates the cause of that look — the grain structure, the spectral color response, the halation glow — using a real-time WebGPU pipeline. No install, no plugins. You open it in your browser and your photos start speaking film.
The science behind it
If you want to understand why film looks the way it does, these go deep on the physics Cineon models:
- Why Film Grain Looks Right and Digital Noise Never Does — the difference between film grain and digital noise.
- ACES Color Space — What It Is and Why It Changes Everything — the modern descendant of Cineon's log encoding.
- What Is Halation? The Science Behind Film's Signature Glow — where film's glow comes from.
