I want to extract numerical values for the separate R, G and B channel intensities, on a pixel by pixel basis, for specific (limited) regions in color photos (JPEG, TIFF, whatever), on a Mac, preferably while I'm viewing the region I'm examining. Any readily available software to do this? Can PhotoShop Elements, GraphicConverter, or Mathematica do it? Thanks for any assistance; email cc of reply appreciated.
