Hey guys! I'm considering purchasing Apple's Aperture to use with my newfound interest in photography. I want to be able to add great effects to the images and edit them a bit more advancedly than iPhoto 6 does. But is Aperture with the money for me? Will it really help me much more? What are your thoughts on the application? All feedback is welcome. EDIT: Oh, and one last question, is Aperture even compatible with my current iBook? Specs in sig.
