I bought some chemistry and mixed D76 and simple acid fixer by myself. And then I developed a short test roll from a Fomapan 400 bulk roll (never tried this one before). The film came out completely blank except for the film leader. Before development I checked the chemistry by cutting the piece of film and developing it under the light, it went black in about 4-5 min in stock solution. Then I tested the fixer, a cut of film went blank in about 40-50 sec. So I developed that roll at 20 C (8 min in stock solution and 3 min in the fixer with a short tap water stop-bath).
I checked the camera shutter as well, there is no problem with it. So what can be wrong with it?
PS. The formula for the fixer I used:
1. 700 ml hot water
2. 250 gr Sodium Thiosulphate.
3. 25 gr Sodium Sulfate.
4. 20 ml 70% acetic acid.
5. Add water to 1 l.
