So, my wife just bought a Canon Digital Rebel XTi, because she'd like to get into digital photography a little more. We are total novices, and we are experiencing one bothersome issue right now. FOR SOME REASON, in the menu system, when we go to the "Quality" setting, we can only choose JPGthere is no RAW setting. Does anyone know why this might be? Any thoughts? What am I missing? Thanks a bundle!
