I have a Canon rebel Xti, and use Image Browser, and DPP, which came with the camera. I've just got back into Mac (previous was a Performa 6400 circa 1997!). Is iPhoto better to use than Image Browser for importing/organizing photos? Should I move up to Aperture? Is Photoshop Elements for Mac worth it? (I don't really want full blown PS) Is there any other software similar to PSE for Mac, which would be roughly equivalent?
