>How can I emulate GIMP's (gimp-brightness-contrast) using >ImageMagick's convert? This is not exactly the same as GIMP, but you might try my unix bash script bcimage at http://www.fmwconcepts.com/imagemagick/index.html In IM, you can control the brightness using the -modulate function (as well as saturation and hue) and IM also has a -contrast function. (My script however, does not use either, but goes at it a more direct way by building a lookup table to adjust brightness and contrast) see http://www.imagemagick.org/script/command-line-options.php Fred
