- colour.models.log_decoding_ARRILogC3(t: Domain1, firmware: Literal['SUP 2.x', 'SUP 3.x'] | str = 'SUP 3.x', method: Literal['Linear Scene Exposure Factor', 'Normalised Sensor Signal'] | str = 'Linear Scene Exposure Factor', EI: Literal[160, 200, 250, 320, 400, 500, 640, 800, 1000, 1280, 1600] = 800) Range1[source]#
Apply the ARRI LogC3 log decoding inverse opto-electronic transfer function (OETF).
- Parameters:
t (Domain1) – ARRI LogC3 non-linear 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 \(x\).
- Return type:
