Define the ARRI LogC3 log decoding curve / electro-optical transfer function.
- Parameters:
t (ArrayLike) – ARRI LogC3 encoded data \(t\).
firmware (Literal['SUP 2.x', 'SUP 3.x'] | str) – Alexa firmware version.
method (Literal['Linear Scene Exposure Factor', 'Normalised Sensor Signal'] | str) – Conversion method.
EI (Literal[160, 200, 250, 320, 400, 500, 640, 800, 1000, 1280, 1600]) – Exposure Index \(EI\).
- Returns:
Linear data \(x\).
