Jerry,
Thanks for that ! I always did my own black and white negatives and photos and still have all the darkroom gear/enlarger. When I had the use of our family colour photo lab in the 1990's I developed and printed the negatives using Konica 801 based machinery (non-digital). This was great fun and allowed for good experimentation/learning.
Thanks Ric,
The Flat Field Camera operating at f/4.0 was a unique design from Lichtenknecker for a reflector and made this sort of field capture a lot easier.
At times focus shift was reported in some reviews of the camera by other reviewers/users, however, I always liked the images that I got.
