Hi Guys,
I'm noticing something strange. Would appreciate greatly if someone can point out what I'm missing...
I apply the any channel (e.g green) onto a separate layer (using apply image command), in effect producing a greyscale image. I notice that if I do this, this layer is generally slightly darker than the original green channel. If do a copy of the green channel to a separate layer (ctrl+2, ctrl+a, ctrl+c, ctrl+~, ctrl+v) , it is lighter. If I do the difference between the apply image layer and the copied layer (difference blend mode), I see minute differences in luminosity (while there should be no differences)
If I do exactly the same thing on a different computer, everything seems ok. It almost seems like it's an issue with a setting.
My brain has frozen now... could anybody please help?
