Still on the same subject,
do you know if there's any way to convert this :

float from_func_AlexaV3LogC(float v) { return v > 0.1496582f ? std::pow(10.f,(v
- 0.385537f) / 0.2471896f) * 0.18f - 0.00937677f : ( v / 0.9661776f -
0.04378604) * 0.18f - 0.00937677f; }

To a curve filter (I guess is the closer thing ...) ?

Sorry if is a silly question, but I really want to make this color
conversion somehow.
Thanks.
L.
