We run a photo "Challenge" contest where we challenge our members to go out and shoot a photo in the THEME of the contest, like this months "Flowers". They must take the photo during the submit period. Archived photos are not allowed. We check when the photo was taken in the metadata. But occasionally someone disallows attaching metadata in their editing software I think. BUT… Seven out of twenty photos metadata indicates a scanner was used instead of a camera. You'd expect one or two to come from a scanner but 30% seems unrealistic. Is this a P.U. error?
