    Was It Sour Cream Or Cottage Cheese? (Casien printing)

    Hello,
    Is anyone familiar with a process that uses Dichromate + a dairy product instead of Gum Arabic for colored prints? I heard a talk on this last year but forgot the details.
    It was either sour cream or cottage cheese treated with ammonia and aged before being combined with dichromate and pigment. I cannot find notes I took.

    Cottage cheese.
    At least with LF landscape, a bad day of photography can still be a good day of exercise.

    Thanks Vaughn,
    I hope that was a serious answer to my serious question.

    Interesting alternative to gum - I'll have to give it a go sometime...

    In what way are eggs anything like a dairy product?

    I was surprised a while ago when I gave up dairy products and quite a few people assumed I was also giving up eggs. I have no idea why.

    Grocery stores here in the USA have for many, many, many years put eggs and milk in the "dairy section" therefore us non-farminging Americans sometimes get confused.

    Didn't you know eggs come from cows?

    Oddly, I've run into similar misunderstandings from people when I tell them I avoid dairy because I'm lactose intolerant. Some just will not accept that an egg is not "dairy" simply because they are grouped together.
