- Parameters:
- Returns:
Canon Log 3 non-linear data.
- Return type:
Notes
Introspection of the grafting points by Shaw, N. (2018) shows that the Canon Log 3 IDT was likely derived from its encoding curve as the latter is grafted at +/-0.014:
>>> clog3 = 0.04076162 >>> (clog3 - 0.073059361) / 2.3069815 -0.014000000000000002 >>> clog3 = 0.105357102 >>> (clog3 - 0.073059361) / 2.3069815 0.013999999999999997
