Histogram Output Oddness
Posted: 2020-11-03T20:35:12-07:00
Hi everyone! I hope you are well during this crazy time. I'm having an oddity with histogram output:
is outputting a fine global histogram, except it has a huge spike in the bin of pure white all the way to the top. It seems this occurs no matter what image I use as input! (I would provide a sample but believe it is irrelevant and will happen for you, too! Please tell me if I'm wrong of course.) I just tried a simple JPG with no odd features, no alphas, no paths, nothing odd.
