I have just purchased the Apple Aperture program for post-processing and manipulation of images taken with a Canon 60 D camera. I'm still very new to this daunting new world of photography, and I was wondering if Aperture would suffice for all the necessary post-processing of RAW images. I'd rather not have to buy Adobe Photoshop as well, unless it's absolutely necessary. Does anybody out there have any experience with Aperture?
