# create-lut

Programmatically generate or bake cinematic 3D LUTs (.cube).

## Usage

```bash
./run.sh bake --ref ref.png --source src.png --output match.cube
./run.sh generate --preset "fujifilm_sim" --size 33
```

## Contract

- **Input**: Image pairs (reference/source) or procedural parameters.
- **Output**: Single `.cube` (3D LUT) file.
- **Dependencies**: `colour-science`, `numpy`, `opencv-python`.

## Features

- **Match Grade**: Calculate a color transform between a reference frame (learned from a movie) and a generated frame.
- **Procedural Simulation**: Apply standard film stock mathematical models (e.g., Kodak 2383).
- **Identity Export**: Generate a clean neutral LUT for pipeline testing.
