Hi gang,

I have just been fussing around changing my standard routine for proofing contac t of (4)4x5 negs on a sheet of 8x10 paper. As I was doing this I noticed that th ere seems to be light fall off. I am set up with the enlarger height and "focus" at the point where a 4x5 neg would be as if enlarged full frame to an 8x10 piec e of paper. I measured it several ways (incident and spot) with my Sekonic L-508 and there is an even fall off of 1/2 EV from center to edge. I was kind of surp rised. Now I don't know if this is typical or will even make much of a differenc e in real world printing. I hadn't noticed any problems with my prints but will go back and look. Despite this I would still love some comment on this from thos e more experienced than I with this finding. Thanks!
