That is a good idea. But where would those other copies be if not in temporary files. He did not see them before.nah, I'm sure it has to do with the camera just storing multiple photos and then downloading them all, like different "folders" if you will on the camera containing the same photos. Try settings on the camera, or if you can, view the photos in windows explorer (Browse contents or open files, something like that) before you download them, and select which ones to download.
Check your camera settings. Make sure you have not enabled bracketing. This will give you three different exposures or three different focus points of the same shot, depending on the camera setting.
So he's taking 3 shots of the same image really fast making him think he has duplicates?
Thanx Guys I am going to check the camera
