I shoot RAW (Canon 7D) and import my RAW files in LR, make my edits, export as JPG and also, just incase I want to go back and tweak my edits I export the file as "orginal" which if I understand it correctly, LR makes a copy of my .cr2 file. I compared the original CR2 file to the copy LR makes and see a slight color difference but that's all.
Is it safe to delete the original CR2 files from my camer and keep the "original" copy the LR makes when I export?
