    First time enlarger question.

    Hi all,

    Today I enlarged my first print and the results were unexpected. The first print came out very dark, with a dark round blotch in the center of the print. I made another print and exposed a shorter time. This improves the result, but still had the blotch. I realized I had forgot to increase my stops by 2 and ran another print with a short exposure time. This was the best but the center of the print still had a dark round blotch.

    This is 120 film, 80mm lens, on a Beseler 45s head. Can anyone offer advice?

    Do you have the upper bellows adjusted for the format you're printing?

    Can you post a photo of the enlarger? It sounds like you're using a color head, on a Beseler. If so, I believe the upper bellows should be collapsed completely (it's been years since I used a Beseler, so my memory may be off). If it's a condenser head, the upper bellows needs to be adjusted for the format you're printing.

    Thank you so much for the tip! I read through the manual and did not see recommendations for bellows usage. Do you have a resource you go to for that?

    For right now I am sticking to 120.

    Thank you again!!

    If you look at this pdf, part no. 20 shows the upper bellows. It should be collapsed as far as possible, when using the color head. I'm not sure that's the problem, though.

    Another thought: I once had a Beseler color head which gave me a similar problem. The diffusion disc, under the color head, had faded in the middle. This caused increased exposure to the central areas of the prints. Take a look. The disc should be even in density across the entire disc.
