So my interest in photography has really spiked in the last few months, so i thought it was time to buy some real software (i hate iPhoto, and preview, is well, just a preview....) I really like aperture so far, but i have a number of questions and "how do i...?s" 1. whats the difference between an album and a project? 2. after i've done editing, how do i save the edit as its own version and get back to the original? 3. is there a way to delete the file itself straight from aperture (much in the way iTunes gives you an option to move file to trash), or can you only get rid of the photo from the library? 4. for HDR processing, Hydra, photomatix, or some other suggestions? 5. is there a way to do that "all black and white except this color" effect besides making it black and white and just unbrushing what you want colorful? 6. after i edited a few shots, they disappeared from the folder i had them in and reappeared in some random aperture library folder. is this a one off or did i do something? if it makes a difference for anything, i have started shooting all RAW, so all answers should be for RAW (if there's a difference) thanks for all of your help!
