Hello,
I used Image->Adjustments->Level to adjust the image histogram. As far as I know, the algorithm for the adjustment of both end side is related to ‘linear stretching of histogram’. My question is what is the algorithm for the adjustment of midtone (the central triangle)? Is it logarithm transformation? Thanks for your help.
