I'm going to try to make this sound as uncomplicated as possible. In an attempt to get more organized with backups, etc, I started a system of putting photos from memory card to a desktop folder with the date. I then edit them in Lightroom. My plan was to then put the folders into one folder, titled photography, then put them on a hard drive after backing up to dvd. One folder contained photos from a wedding. That folder had photos from the first memory card and a folder within it with photos from a second memory card. However, after moving them and telling LR where the photos were from the first memory card, it lost photos from the second memory card. I have the original RAW files, but LR doesn't have the edits. I tried "undo" to no avail. Am I screwed? Do I have to go through and re-edit? Thanks in advance, and I hope that was pretty clear.
