Hey everyone, I hope you can help me figure this one out, please bear with me
It was not the first time I developed b/w film, but it was the second time I work in this lab, which is in a new school. I'm still pretty inexperienced though.
So I did the usual, developed my Agfa APX 100 with APH 9 for 5.5min at 20ºC (1+25), then stop bath and fixer, everything went fine. Then the film came out blank, without the rebate and the leader, just completely empty, and with a slight greenish tint to it. First I thought I could have switched up the stop bath and the fixer, but it wouldn't explain that result. Unfortunately, the person responsible for the lab was sick, so we had their assistant (who is also a student but with more experience) there to help and no one had seen that happen like that before.
I then asked someone who at least knows a little more than I do, and they said I must have switched the developer with the fixer, which I am sure didn't happen. I found this link that mentioned a similar situation and pointed to the same conclusion: I fixed the film without developing it. (Black and White Film Development Problems.)
Ok, I was sure I developed it first, I confirmed several times the dilution and the temperature, etc., but then I realised I should have gone with what my gut told me when I measured the developer, as it was a little too brown (there were two bottles of the same developer in use, I used the one which seemed to have less product inside because I figured we should use it up, the other one was half way full). And it was a little thick. I should probably mention although I have developed film many times, usually the same recipe anyway, but I don't usually so the dilutions, it's often someone else. So I am not that familiar with the changed with the product over time or in other situations. I went ahead with the process anyway because it was a test roll, not really important and I could afford to mess it up. My gut was telling me that it'd not turn out ok, but I also wanted to see what would happen.
Of course, I'll ask my teachers and technicians but this was the last day of school, now come the holidays and you know, the answers might take a while. Anyway, I think what must have happened is that the developer had gone bad, in which case I don't know why it was there, or if some other student messed it up. In that case it wouldn't have had the strength to develop the film and it was just fixed afterwards. That'd make sense, but I don't really know how bad developer behaves, it just seems that ate least some image should be there, even if barely.
Sorry for the long post, I just wanted to be as descriptive as possible. Thank you. Soph
