I don't like making contact sheets, but I do like having contact sheets as reference material so I do it. I don't have a problem judging exposure and contrast by reading the negatives, but it is a lot easier to decide which frames to print with the contact sheet as a guide. Filing is a lot easier with a contact sheet too, and when you go looking for an old negative you want to reprint, well what would you rather do? Would you rather examine strips of negatives or a sheet of small prints at once?
