Hi All, I'm completely new to Aperture and currently having a lot of fun with it. But i do have quite a few questions. I will try to make them ones that are not immediately obvious for a total beginner, but please bear with me. 1) My guess is that Aperture does not make changes to the original file and all changes made are via Aperture. In other words, only photos exported from Aperture will have changes you've made. Is this right? 2) I'm thinking that the auto enhance is an algorithm. Does that mean that it will give you the same results every time you use it? I have this photo that is kind of over exposed. When i click enhance, it goes dark and then I have to click it again to get the right result. Is this a bug or something wrong with the particular photo. 3) I'm sort of getting the hang of the sync feature with facebook and flickr. Will changes made in facebook and flickr be made in Aperture as well. I probably have some other questions but this will do so far. Many thanks.
