Recently got my iMac and purchased aperture. I would really like to get more into photo editing for personal enjoyment. I figured aperture would probably work best for me and what I'm looking to accomplish. Was wondering what would best suit me. I have a track pad and mouse but, I hear that one of those bamboo tablets are the only way to go. Does anyone have input of the necessity of one of those? Is it necessary and would it really be facilitated for me being I'm not really using ps?
