Does anyone one know how to read the histogram values produced by Achemist

Indexes are luminosity levels on scale 0-255
The value of each item is the number of pixels with that luminosity.


So in the above screenshot, there are 5400 pixels with a luminosity value of 13

Is this correct @Jarda

Thank You @Jarda I should be able to use those values now.

Bonus question :slight_smile:
I didn’t notice this, but is there a way to get separate histograms for R, G and B channels?

Yes. Instead of document instance, you will ask the channel for histogram. So histogram of e.g. red channel.
