colour.models.log_decoding_SLog3

colour.models.log_decoding_SLog3(y, bit_depth=10, in_legal=True, out_reflection=True)[source]

Defines the Sony S-Log3 log decoding curve / electro-optical transfer function.

Parameters:
  • y (numeric or array_like) – Non-linear Sony S-Log3 data \(y\).
  • bit_depth (int, optional) – Bit depth used for conversion.
  • in_legal (bool, optional) – Whether the non-linear Sony S-Log3 data \(y\) is encoded in legal range.
  • out_reflection (bool, optional) – Whether the light level \(x\) to a camera is reflection.
Returns:

Reflection or \(IRE / 100\) input light level \(x\) to a camera.

Return type:

numeric or ndarray
