    Out of Stop, switch to water?

    Hi.

    I have been using Ilford Ilfostop when developing PF4Plus. But I'm just about out.

    Should I just switch to using water for the Stop process and save the money?

    Thoughts?

    Same here. After years of water only, I've found Ilford Multigrade paper likes a good stop or I risk some weird marks and colors on my prints. Film is still water. Paper is citric acid, as Tin Can noted. Buy a 5# bag from Amazon. No stink.

    Stop is the least expensive of the chemicals because it is diluted so much and keeps well. It's basically just acetic acid (pus a dye for indicator stop).

    People do forgo stop - if you know what you are doing and are prepared to deal with process changes. But it may shorten the life of the fixer due to developer carryover. That can negate the minor cost savings anyway.

    I use plain fresh water with my TF-5 fixer per spec. Fixer lasts plenty long

    Water stop for film. Acid stop for paper. I use citric acid like the others. About half tablespoon per liter of water. White vinegar is also an option. I've not used that so I can't recommend a dilution. Do a search or maybe someone will chime in here with that info.

    In the USAF photo school at Lowry they sent us to the chow hall for vinegar that we diluted.

    I've always used plain water, two rinses.

    Two rinses each for how long? Any agitation?

    Oh, myabe 15-30 seconds for the first rinse, 5-10 seconds for the second. I flip the tank over a few times, the idea being to wash the developer off the film.
