Thanks for the tip. Do you know whether that approach provides the mean (median,
etc.) luminosity value before or after desaturation? It looks to apply the
effect so it's unclear to me. If the program applies it uniformly across all
images I may be able to use it as a proxy for luminosity but would like to avoid
that if possible.
