Hi, I was doing some printing of 6x6 B&W negs with an LPL 7700 Pro enlarger with a Schneider 80mm enlarger lens. I noticed fairly significant light fall off in the corners of my prints. The negative density looks pretty constant all the way across so I am pretty sure that it is not the negative that is causing the problem. I have not used this enlarger for 6x6 MF before but I was using it for 35mm (with a 50mm lens) with no problems before i simply switched lenses and neg carriers. Is there anything else that I should have adjusted on the enlarger in order to set it up for 6x6? I suspect there may be something else but without a manual I can't be sure. Can anyone help? Please don't suggest burning in the corners. I am looking for responses that positively address the enlarger configuration. I want to make sure my set up is correct before I resort to "work-around" measures. Thanks and regards, Thanasis.
