A photographic enlarger can be fun when producing contact sheets or enlargements of slides. However, most people interested in this process are attracted to it by the lack of bulky or expensive equipment, so I’ve not had many questions concerning enlarger use. I’ll eventually write something up on my experiences with an Omega enlarger and blueprint paper, but in the meantime, here are a few notes.

• Use a positive film (slide film), or you will get a negative image.
• Use a bulb with good UV output, like an uncoated halogen bulb.
• Glass blocks UV, so expect your exposure to take a LONG time.
• The smaller the enlargement, the more light makes it to the paper.
• 6×6 enlargements tend to take less time for the above reason.
