colour.models.log_decoding_CanonLog3

colour.models.log_decoding_CanonLog3(clog3, bit_depth=10, in_legal=True, out_reflection=True)

Defines the Canon Log 3 log decoding curve / electro-optical transfer function.

Parameters:

• clog3 (numeric or array_like) – Canon Log 3 non-linear data.
• bit_depth (int, optional) – Bit depth used for conversion.
• in_legal (bool, optional) – Whether the Canon Log 3 non-linear data is encoded in legal range.
• out_reflection (bool, optional) – Whether the light level \(x\) to a camera is reflection.

Returns:

Linear data \(x\).

Return type:

numeric or ndarray
