    I hate the smell so I use Ilfostop (odorless) for paper and water for film.

    I couldn't think of anything witty to say so I left this blank.

    Hello, I buy a gallon of Glacial Acetic Acid, make a 28% stock solution and then dilute from there to a working solution. It is really cheap and I only buy Glacial once or twice a year. To make 28%, dilute 3:8 or 9oz. Glacial to 24oz. water. To make a working solution dilute 48ml Acetic Acid(28%) to make 1 liter. Hope this helps, Ken

    1:3 seems rather intense... Does this equal anything like a 1% - 2% solution of acetic acid?
    This is a quote from Richard Knappow from Pure-Silver responding to a similar question.

    Most of the distilled white vinegar I've examined locally in New England, is 5%
    acetic acid. That should be diluted with two or three parts water to one part
    vinegar to keep it in the range of commercial formulas. The concentration
    does vary with location but is usually printed in the bottle.
    Kodak SB-1 is 48 ml of 28% acetic acid per liter, or 0.28x48/1000 = 1.3%
    5% acetic acid in vinegar diluted 1 + 2 is 5/3 = 1.6%,
    or if diluted 1 + 3, 1.25%.


    I have no idea about color processing.

    I keep in stock Kodak's acetic acid which I dilute according to the bottle's instructions. I use it while making prints in my darkroom, but since I prefer to subject my films, during processing, to as few foreign elements as possible, I use only water as a stop bath which is at the same temperature as the developer and fixer. This has never caused any film development problems at all.

    Myself, I use either this or acetic acid.

    What are the pros and cons of stop bath vs. plain water.

    Personally I don't think Bath should be stopped at all. It's a great place with lots going for it!

    Sorry for this fault...

    ...I still do not understand why a perfectly nice print which looks stunning in the developer needs to be fixed afterwards....If it ain't broken, don't fix it...right?

    That's a great line, Morten! I suppose I should expect no less from the High Priest... Praise Rodinal!

    I am moving to an alkaline fix regime for both films and prints so will be using a plain water stop. However I used a very similar citric acid mix to yours. I found it effective, odourless and very economical. Like you I used once and then threw it away. I will probably contiue to use stop bath for colour prints.
