So I am trying to figure out why iphoto is now not giving me the option of adjusting my photos contrast,sharpness,color , etc. It worked fine when I first used it. Now, for some odd reason, I get nothing. Only thing I have done is installed my canon sd 600 software cd so I can upload videos I take with my camera. I am stumped. Anyone have this problem? i can crop and use all the other buttons just not that one which really bums me out as that I the one I am most apt to use. Things that make you go hmmmmm...
