This question may be a little off the beaten path. I am looking for a system to present my 4"x5" contact prints for my portrait work. I use a 4"x5" camera and would like to find a way to show the client a finished proof. I have in the past just mounted the print on a 2ply window matt with a 2ply window. This is a tad bit labor intensive as the proofs are just that..proofs. Anyone have a better idea? I am not looking for a major investment. Something that looks good and is functional. Thanks in advance.
