colour.models.log_decoding_SLog2#
- colour.models.log_decoding_SLog2(y: FloatingOrArrayLike, bit_depth: int = 10, in_normalised_code_value: bool = True, out_reflection: bool = True) FloatingOrNDArray [source]#
Define the Sony S-Log2 log decoding curve / electro-optical transfer function.
- Parameters:
y (FloatingOrArrayLike) – Non-linear Sony S-Log2 data \(y\).
bit_depth (int) – Bit depth used for conversion.
in_normalised_code_value (bool) – Whether the non-linear Sony S-Log2 data \(y\) is encoded as normalised code values.
out_reflection (bool) – Whether the light level \(x\) to a camera is reflection.
- Returns:
Reflection or \(IRE / 100\) input light level \(x\) to a camera.
- Return type:
