I developed the first film that my neigbours son shot with his inherited Canon AE-1. The result is dreadful. Can anybody tell me what could have happened? T-Max 100, Rodinal 1+50, 20°C, 12 min, 60/60-3x. 1 min stop in water, 4 min fixing in new Kodak F-24. I know the combo is not ideal but I had nothing else but Rodinal. He took only 29 pictures. The resting frames are totally blank without any exposure traces on the films edges.
