Tri-x.deardorff.pinhole.test.jpg
Today I did a pinhole test by fitting a 0.5mm James Guerin pinhole into a lensboard for the Deardorff, and shot an 8X10 sheet of old Tri-X a friend donated to the cause. Focal length (determined by bellows extension was approximately 6", making this an f307 "lens". The exposure was 6.5 minutes under heavy overcast conditions. The Tri-X was developed in Rodinal 1:25
