Found this via the New55 team. Great instructions. May I askhow many negatives can one batch of the fixer solution handle? For example, if I pour some 50% solution in a tray and process one negative, can I clear additional negatives in that same solution and if so about how many? Do I just go by how things look? I'm not talking about storing used solution, btw, just whether I can clear multiple images in one session with the same batch of solution in a tray. Thanks.
