colour.models.log_decoding_VLog

colour.models.log_decoding_VLog(V_out, bit_depth=10, in_legal=True, out_reflection=True)[source]

Defines the Panasonic V-Log log decoding curve / electro-optical transfer function.

Parameters:
  • V_out (numeric or array_like) – Non-linear data \(V_{out}\).
  • bit_depth (int, optional) – Bit depth used for conversion.
  • in_legal (bool, optional) – Whether the non-linear Panasonic V-Log data \(V_{out}\) is encoded in legal range.
  • out_reflection (bool, optional) – Whether the light level :math`L_{in}` to a camera is reflection.
Returns:

Linear reflection data :math`L_{in}`.

Return type:

numeric or ndarray
