    Homemade Stop Bath Recipe

    Does anyone have a "recipe" for making stop bath for B/W paper developing? It is almost impossible to buy commercially in my local area. Thanks, don

    You could always use water as a stop, there is a group who think thats the way to go!!!

    I normally use a acid stop but when processing Efke/Adox I use water and get great results!!!

    Just a thought.

    I use water with film (I use an alkaline fix so this is preferable) but I use stop bath with prints.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    One tablespoon of citric acid in two liters of water. Less smell, more capacity.

    Edit: That's pretty much the same as "ath" said.

    One part common white vinegar to 4 parts of water = 1% Acetic acid solution.

    Smell...? I guess there are those who are extremely sensitive to the odor of what is an extremely *weak* salad dressing.

    Where do you buy citric acid? Is it a grocery store item?
