To clarify my comment on photoshop. It was ONLY to refute the comment that the presence of a carrier edge PROVES that the print was made from film. My argument was that the same effect can be applied to a digital image and therefore negates the quoted statement. In other words a digital image can be made to LOOk as if it was a film image. Nothing else should be inferred from my statement.Inclusion of the negative carrier edge in your print also identifies the print as a projection print made from film.
