Question

For what it's worth, I think everyone needs to watch the Aperture tutorials prior to some of the posts here. I see some questions that can be answered just by watching these tutorials.
One example
e.g. selective coloring/desaturating etc.

Answer 1

I'm glad so many of you are willing to help less fortunate, beginning users like me.
So... I have a question, several really:
1) I've imported my pictures into Aperture from my camera. But now I don't know what to do.
2) I want to take a person's face from one picture and put it over someone else's face in another picture - how do I do that?
3) I imported a black and white picture (jpg), how do I add color to it?
4) I'm looking at a picture, pressed some buttons in panels, and have what I consider an improvement. I can't find a way to save the picture. Luckily the next time I open AP, the change is still there. I thought this application did not change the originals? Help - how do I get my original picture back.
5) I want to have a second picture of an original that is edited differently. I've reimported the original so I can change it (see question 4), I can't find a way to get the original back without reimporting it. However, AP won't let me do that, says it's already in the library. Well, duh !!, yes it is, but I want another copy of it so I can edit it differently. Talk about not being intuitive!!
6) And speaking of editing, how do I crop (is that the right word?) a photo? My printer just prints the original size, it can't produce a smaller picture.
7) I left the original images in the folders they were in when I imported. However, after importing into AP, I reorganized my folders and albums in AP, albums: whatever they are (same as folder I guess, nobody here has mentioned the difference between them). When I go into finder, I discover the old folders still there in the original layout, but not the changes I made in AP. Is this a bug? Must be. Anyway, I used finder to change the folders around so they are in the same organization as in AP, and now when I look a photos in AP, it tells me it can't find the photos. ARGGGGGHHHH!! So I figure I'd delete all the original folders in finder and later tried to export all the photos in AP back to new folders in finder. But AP tells me it can't do that. How do get my photos out of AP???? I know they're there, I can see them!
8) Should I be backing up my files? I never have and have never lost a single file in the two years I've had me mac. Hmm... now my drive has this ticking noise. I think I'll reformat the drive to get it back to the way I had it yesterday. That should also get rid of the ticking, right?
9) I'll post more questions after the format has complet
