Alright so for years I had a hybrid workflow where I would scan my negatives but finally picked up a darkroom setup. It's a Beseler 23C with a dichro head. I set everything up (power supply, Gralab 645 timer, etc) and figured I would throw in a 6x6 negative to see what it looks like on the baseboard. There is a Beslar 75mm lens on the enlarger currently and even with the head moved all the way down, here is what I get. What am I doing wrong? From my research, 75mm should be fine for enlarging a 6x6 negative. Please see attached for image.
