Ok I am not 100% sure that I am correct here Sam, but this is my elementary understanding....
When you upload to LR it puts it in a LR Catalog (one ongoing catalog that you continue to upload to) This is where all of the alterations are stored, I think. But you still only have your one copy of your photo on your computer. Once you alter, fix, crop, etc your RAW files, you export them as a .jpg. Now you have 2 copies 1 raw, 1 jpg. I dont think it is any different than processing Raw in bridge or ACR. But now you have a LR catalog.
I am not sure any of that made sense.....maybe Katrina has a better handle on the organzation aspect of LR.....its still hazy to me....apparently.
