Hi Brian

I checked a couple of ImageMagick books I have, but found nothing explaining the 
histograms. I did not try reading the source code...

Could you upload the histogram output of the 3 programs, on the same image, 
side-by-side? That might tell us something.

Also, since I don't have GIMP or Photoshop installed, I don't have access to 
their on-line help, but perhaps their web sites explain these 'levels'.
