colour.models.log_decoding_Log3G10

colour.models.log_decoding_Log3G10(y: Domain1, method: Literal['v1', 'v2', 'v3'] | str = 'v3') → Range1

Apply the Log3G10 log decoding inverse opto-electronic transfer function (OETF).

Parameters:

• y (Domain1) – Log3G10 non-linear encoded data \(y\).

• method (Literal['v1', 'v2', 'v3'] | str) – Computation method.

Returns:

Linear data \(x\).

Return type:

numpy.ndarray

Notes

Domain	Scale - Reference	Scale - 1
y	1	1

Range	Scale - Reference	Scale - 1
x	1	1
