colour.models.log_encoding_Panalog¶
- colour.models.log_encoding_Panalog(x: FloatingOrArrayLike, black_offset: FloatingOrArrayLike = 10 ** 64 - 681 / 444) FloatingOrNDArray[source]¶
Define the Panalog log encoding curve / opto-electronic transfer function.
- Parameters
x (FloatingOrArrayLike) – Linear data \(x\).
black_offset (FloatingOrArrayLike) – Black offset.
- Returns
Non-linear data \(y\).
- Return type
Warning
These are estimations known to be close enough, the actual log encoding curves are not published.
