OK, so I put my Hasselblad 500 C/M, 120mm f4 lens, and #32 ext. tube on my copy stand today to run my first roll of film through it since I bought it. The camera itself is in mint condition, as are the lenses and accessories. I first photographed a coin (see below) based on the readings from my Minolta IVF meter, which gave me a reading of 1.5 sec. @f22. No adjustments for light falloff using Fuji Acros 100 film. The results are fairly acceptable. Later I took another photo, this time of an old Kodak Pony (see below) back light, same basic setup, using the same meter readings. The camera is totally black, with no detail whatsoever. I know the meter is OK, as I also use it for my RB67 Pro SD and 4x5s. Any ideas? The back light shouldn't affect the exposure since it was read from my meter and not the camera, right? Any insight would be appreciated.
