    I stopped using Photo-Flo years ago and switched to Edwal LFN. Edwal calls for two drop of LFN per one pint of distilled water, and is reusable for quite some time.You can also add one drop of LFN to developer to eliminate bubbles from forming on film during development. IMO, a far superior product to Kodak's.

    200ml PhotoFlo to 1ml water? Wow!

    I use it at 1.5 ml photo flo to 500 ml of water. At any higher concentration i get photo flo marks on the film after it dries. I use distilled water, but even when i didn't i had the same problems.

    I do 1:300. Seems to work for me. With my current water, 1:200 was too much, and less than 1:300 wasn't enough.

    It works out to 1 drop from my dropper per oz of wash water, so it's easy to measure.

    Kodak recommends 5 ml to 1 l of water and The Film Development Cookbook recommends only 1 ml to 1 l of distilled water. I use as little as 0.5 ml to 1 l of distilled water, and it works fine for me. However, what really interest me is what other dilutions people use to avoid water marks without getting marks from Photo-Flo itself.

    Being a rocket scientist could help, though.

    One drop per ounce is probably more like 1:350 to 1:560.

    My mix is 2.5 ml per liter with 50ml rubbing alcohol. I have softened and filtered water.

    However... I use LFN if I can instead. Recommended amount but still add 50ml of rubbing alcohol.

    Technology is not a panacea. It alone will not move your art forward. Only through developing your own aesthetic - free from the tools that create it - can you find new dimension to your work.
