I am behind the times. I just got my first digital camera and am trying to get started using iPhoto 4. I am having trouble figuring out how to get a photo into an edit mode where I can do simple things like red eye reduction. I can view my photo in library mode and then double click it, opening it in another window (supposed to be an edit window). But no matter what I do, the red eye tool button remains grayed out. It seems like I can never actually get into an edit mode or window. Any suggestions? Thanks.
