I’m the main developer of a commercial camera profiling software. So far mostly focused on still cameras, but next release will contain video features, cube format etc. We have built in gamma for the usual suspects like Arri Log-C, Sony S-Log, Canon C-Log etc, but also gammas for action cameras and drones like GoPro Protune and DJI D-Log. I’d like to include Parrot P-Log as well, but it seems to be impossible to find an actual definition of the gamma, that is an exact mathematical formula of how to convert from P-log to linear reflectance (or the other way around).

Could someone help me with this?
