Originally posted by shutterpuppy OK,call me stupid but I have no idea how one could alter the EXIF data. Seems like it would put a lot of photo contest is jeopardy i.e. I could scan a National Geographic photo of a lion and her cub from the 70's and say I took the picture last week. Ahhh I can smell the lawsuits already.
Pretty much any decent image management program can alter EXIF. people do it all the time to correct wrong dates set in the camera, wrong lens info if they entered the wrong SR focal length or had SR turned off (for manual lenses), to enter copyright info, etc.
And yes, it does mean people are on the honor system in entering contests.
