Mary I started doing just that/duplicating,,,over time I lose sight of which is the original,..I have so many different versions of an original photo that I completely lose sight of the original, Some are edited in iPhoto, some have been transferred to Flickr and edited and I have Pixlr, Its becoming difficult keeping up with things. A case of "ADD" for sure, I should have stayed with my original setup.,, storing my photos on the memory card on my sony,,,those images are original/unedited,,,but it became difficult to transfer images over to iMac.iphoto because my reader had to read through all of my photos in order for me to select the ones that i wanted to transfer over (that had not been transferred before). Now I delete the photos on the memory card on sony after I transfer them to iPhoto,...This whole photography thing is new to me,..I had been focused on camera settings/and all of the other intricacies associated thereof, Now I am hoping I can get really organized ...I think I just answered my own question, Maybe I should just transfer all of the camera images into another file (the original unedited ones) and make a copy of them to I photo,,,That way I can always know that I have the original version if I want to start over....is that plausible?
