[QUOTE="chas_m, post: 1306598"] He was technically correct in a way, but generally that answer is wrong. Perhaps what he meant was that you can make all the edits you want to a picture and your "original" is never actually touched -- if that's the case, then he's right. But that's not the same as truly "nondestructive" editing. iPhoto (interally, not obvious to the user) makes a dupe of the photo when you start editing it -- so you have an "edited" copy and the "master" copy so that you can always "revert to original." But the edited one, if it's a JPEG, is re-saved each time you perform an edit and then move on to another picture, which diminishes quality. I don't know if that's the case when the "original" is a TIFF. I assume iPhoto would save it back as a TIFF and thus you don't have to worry about quality. Overall, iPhoto is an adequate but not idea program for someone who is going to be working almost exclusively in RAW *and* wants to do a lot of editing. I'd suggest something like Aperture or Lightroom for that, perhaps with Photoshop for more serious editing. [/QUOTE]
