I never delete the RAW file of any image that I might conceivably want to pp. I don't save edited RAW files - I always always always save as TIFF. I have gone back and re-worked images that I took five and sixyears ago on my Canon D60 because I wanted a different look. And I never know when I might want to use a different image other than the one I pp'd after the shoot.


I hope this helps.
