    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.

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

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

    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?
