I was attempting to enlarge 35 mm negatives to 11X14 with my 23C and 50mm lens. I found that I cannot focus the image when going that large. The bellows are compressed to the limit. If I crank the enlarger head down a bit I can focus the image though the image is roughly 10X12. Not as large as I would like them to be. Is there a way I can get larger images from 35 mm negatives using this enlarger? Regards.
