Hey, all. I know what RAW is, but I have a question regarding the processing procedure. I edited Picture#1 on a computer using Lightroom 2. I exported it as a JPEG that's resized, but I want to print it now but it's too small imo. A few months ago, I transfered the edited RAW Picture#1 from computer to an external hard drive then deleted the Picture#1 from computer. I open up the Picture#1's original RAW from external hard drive with a different laptop and it is now unedited. I assumed the RAW file get's "saved" each time I edit it because when I would exit Lightroom and open it up again, it would have the changes made. Is it because it's a different computer that's why the changes made doesn't show up? should I just overwite the edited pictures whenever I finish working on them? How does "virtual copy" work? I don't really want to overwrite original RAW for obvious reasons, but I also don't want to have 2 copies of the same RAW with edited versions and non-edited. That's too much space. can I "copy" virtual copies to an external hard drive? thanks.
