I have downloaded the trial of Aperture 3 and I have some (probably basic) questions about how it works. I haven't really used the trial in any great way yet, not had the time, will do over the weekend.

Anyway my questions, when you start to edit a photo does it make a copy and store it on your library? i.e. is it going to use twice as much HD space as just keeping the edited version?
I see the function to revert to Master, I guess that is the Original RAW?
 
Is it not the same as Lightroom then? n Lightroom there s one copy of the file and then a side file that contains the database of image amendments - the xmp file is very small.
 
No it doesn't create 2 copies. It just remembers the changes you make. You can create several different versions of the same image, but all it does is remember any adjustments, and saves them in a much smaller file.

If you decide to edit an image with, say, Photoshop, or a third party plug-in, then it will create a 2nd copy of the image, leaving the original in its current state.

Hope that makes sense.
 
yes same as Lightroom. A small database file contans all the relevant information and when using Aperture it will refer to the file to recover any amendments you made. Delete the database file and you will lose the amendments but not the original image.The virtual copy is the same image file with a different database file.
