colour.models.log_encoding_NLog¶
- colour.models.log_encoding_NLog(in_r: FloatingOrArrayLike, bit_depth: int = 10, out_normalised_code_value: bool = True, in_reflection: bool = True, constants: colour.utilities.data_structures.Structure = NLOG_CONSTANTS) FloatingOrNDArray [source]¶
Define the Nikon N-Log log encoding curve / opto-electronic transfer function.
- Parameters
in_r (FloatingOrArrayLike) – Linear reflection data :math`in`.
bit_depth (int) – Bit depth used for conversion.
out_normalised_code_value (bool) – Whether the non-linear Nikon N-Log data \(out\) is encoded as normalised code values.
in_reflection (bool) – Whether the light level :math`in` to a camera is reflection.
constants (colour.utilities.data_structures.Structure) – Nikon N-Log constants.
- Returns
Non-linear data \(out\).
- Return type
