Histogram Bezier plugin uses Log instead of Linear.
That is correct per GG.
I don't understand what type of histogram View Scope tool uses in its
Histogram? Log, Linear or 50%?
He says "Log".
When the Color Model format (in Settings->Format...) is set to RGB[A]
the histogram displayed on Histogram plugins is the same as on Histogram
Bezier plugin.
If you change Color Model format from RGB[A] to YUV[A] the histogram on
Histogram Bezier no changes, but on Histogram plugin and on View Scopes
it changes. It is strange, I think.
He is looking at the code this afternoon and so far reports that the calculation is done a little differently in Histogram Bezier than the other 2. But still looking and I am not sure I will be able to convey what the difference is.
