Hi All,
I've just joined the forum and had a quick search but couldn't find the answer to my question.
I am using the select by color tool to map light intensities from different photos. I can select regions of different brightness and can adjust the threshold level to widen or narrow the selection, all this I'm fine with.
When I make a selection, the luminance is plotted on a histogram which shows the range of values the current selection is in. My question is; is there a way of setting the luminance values to drive the selection? I want to copy the selected regions and compare them so I want to ensure I have the same luminance values for the photos I'm comparing.
[edit]: I am using 2.10.14
Thanks in advance
Mark
