Hello, I've recently purchased a Macbook Pro and I would like to begin using a more sophisticated program for managing and editing my photos. I have a Canon T2i and would consider myself a novice photographer, though I have a rudimentary understanding of aperture, shutter speed, white balance, ISO, etc...I have read Bryan Peterson's "Understanding Photography: Field Guide". I have downloaded the Aperture 3, 30 day trial, and I am happy and impressed by the program. Further, I am OVERWHELMED by the program. I spent some time watching the tutorial videos on the Aperture website, which have been moderately helpful, but they did not provide the direction I was looking for. I am mainly overwhelmed by the editing options and was wondering if any of the forum regulars knew of good resources for learning the program, i.e. books or websites. I've noticed that Selby writes a lot of books for the Adobe programs, is there a good author that writes about Aperture? From what I understand, most post-processing is mostly subjective. Currently, I don't trust my judgement when editing a photo because I have this underlying feeling that I am "not doing it right". My thought process is that, "there have to be certain rules or adjustments that everyone uses...maybe a formula..." I don't know. Anyway, now I am rambling. Hopefully someone can help me out. I definitely appreciate your time and advice. Thanks.
