Just bought a Yashica MAT-124G at a camera swap. Looks to be in mint condition. I am not familiar with medium format cameras. Loaded some Kodak TMAX 100, 120 format into the camera following the instructions. Took 12 pics. Developed the film in standard TMAX 1:4 developer etc. When I removed the film from the tank, it was completely blank. Completely transparent. Any ideas?(posted 8218 days ago)
