Today I screwed up another two rolls of film processing them. I don’t understand what went wrong. You should be able to re-use the developer and fixer, and I have done so succesfully before. Yet this is the second time in a row that my films have come out blank re-using chemicals. Same brand of chemicals, same processing machine.
First time this happened I thought it was because I didn’t increase the processing time that second run. This time I did increase it (the amount stated in the manual of the chemicals), and it still came out blank. So what the hell am I doing wrong? I’t can’t be the temperature, that is handled automatically by the machine.
Here are the details of my processing run:
- I ran the cleaning program beforehand (I succesfully developed B&W film yesterday)
- I used Tetanl 2 bath chemicals (developer + bleach/fix) that had been used once before
(before using them the first time, I cleaned the hose that drains the chemicals, to prevent bleach/fix getting in my developer)
- developing time: 3.45 minutes
- bleach/fix time: 6 minutes
- result: blank film
If anyone can give me an idea what went wrong, I’d greatly appreciate it.
