Good Afternoon Again, Chuck,
I just went back and looked at your two photos. That's a fairly extreme problem, which, as I indicated just above, I've never encountered. Also, I just checked and found, not surprisingly, that the light circle I get is a little over 6 inches with the condensers just above the marked 4 x 5 position. I still try to shoot without extremely tight composing, but corner to corner illumination coverage for the 4 x 5 carrier isn't a factor.
