Since I'll be moving soon-ish I decided to print a few 8x10 negs of mine before everything is sold or stored. 99.9% of my printing w/that enlarger was rolls of 35mm film making enlarged proofs for clients. Whenever I did that, I had to burn the corners 2-3x to get them even w/the center of the print. I attributed this to the 240mm lens I used being too short and doing some vignetting. I didn't do enough of this type of work to make the investment in a 300mm worthwhile. So I printed a couple negs and there was no burning needed whatsoever. Landscape shot, studio shot all perfectly even. Same 240mm lens, same diffusion chamber, etc. It's a DeVere 5108 tabletop model. So what gives? The proofs definitely needed burning on their corners whereas these normal prints from 8x10 negs needed absolutely none. Eric
