Hi
I have a Pentax 67 and a Mamiya 67. I use both cameras without and with tripods depending what I want to shoot. I use the M67 for mountain climbing because of much less weight. However the P67 is better for general use.
apx100 testing problem
in Black & White Practice
Posted
I am currently testing the Agfa APX100 with Kodak X-TOL 1+1. The
results are excellent linear density curves for N, N+1 and N+2. The
problem comes with N-1. I have got a upwards bended curve. Then I
have repeated the test with X-TOL 1+3 and got the same result. For
instance at N-1 I got for Zone I a density of 0.12, for Zone V a
density of 0.8 and for zone IX a density of 1.18. However the density
for zone V should be 0.69 in this case. Should I better use Rodinal
1+50 for the N- region? I am working with 4x5".
