Hey,
Yesterday after processing my film I noticed a weird "sediment" on my negs that could only be removed by either rubbing it off (bad idea) or by using a rather powerful stream of water. I didn't think anything of it until I saw the dried negs.
Where the sediment was, there is no pyro stain (in a streaking pattern) but it's clear that the development happened.
Question 1)
So, I'm wondering if there's a way to do something with the negs so that this weirdness doesn't show in the print... e.g. remove stain and then re-stain.
Question 2)
I've never run into this problem before and my working method has stayed the same (efke 25 in PMK 1:2:100 @ 9.5 min. slosher tray agitation every 15 sec. 30 sec water stop. 5min fix. 2 min stain with agitation every 30 sec) though I did just buy new developer (PMK liquid from B+H)
I seem to remember reading something about bromides releasing when using pyro and causing uneven stain. Could this be the "sediment" I saw? Is there something else I should check?
Finally, the photo dept's tap water gets filtered before it comes out of the pipes and the filters were replaced at the beginning of the month. I'm not so sure the sediment is coming from the tap.
Thoughts?
Thanks
