Exactly the point.....at least from a wedding and portrait photographer standpoint.....clients order normal size prints....it must because they recognize what 5x7 or 8x10 or whatever is. Rarely would they make that large of print or at those sizes. Many of the standard ordered prints are going to be cropped. 4x6 normally end up as nothing more than quick proofs. Then also when you order borderless prints, the extreme edges are cropped off almost all the time to make sure they are borderless with print machines.
