    We had people from the left coast as well as England attend. It's like that with all our workshops. Denise Ross is much closer to you...ask her to do a workshop.

    More Images from our Recent Emulsion Workshops

    More pictures from our two recent bromide emulsion workshops. We had a real mix of crazy weather both weeks. Still, we made over 100 negatives and had some very nice test plates.

    Yes, I'd like to thank you all for your hard work running the workshop! I really enjoyed it and look forward to making the emulsion we learned at home (I' gathering what I need)

    Can I ask a silly question, I've never considered making my own emulsion to coat plates, film, paper, etc., but why does it seem that the workshops I have seen that create materials create types that are not often avail (eg a bromide only paper, which I believe is only made in matte by Slavich, AZO which only one company sells, or a slow ISO film 25 or so - which is not even made anymore, I think)? See my point? It's like these workshops teach how to make materials that are limited or impossible to get!

    Disclosure - I'm a fan of slooooowwwww film and bromide paper! Why's it seem the few places making this kind of great goods is at these kind of workshops?! I think you all are drawing me in

    Would love to make a tips to Rochester to see where it all began ( in the states at least)

    Andy;

    Each emulsion is specific to a given target purpose. Also, you cannot run before you walk. So, you learn in stages and you move in the direction you want most. A paper emulsion is AgCl or AgClBr. A film emulsion is AgBr or AgBrI and the method to make them is different.

    So, if you ever get oranges from an apple tree, let me know!

    Actually I had no problem finding the chemicals required at Artcraft Chemicals or Photographer's Formulary with the exception of thymol. I spoke to a nice lady at Photographers Formulary today and she said suppliers only want to sell them huge amounts which used to not be the case. The only expensive material is, as you'd expect, silver nitrate. Is there a substitute preserative for thymol???

    You can do without Thymol if you use the emulsion right away (within about 1 month). After that, all bets are off.

    It was a great workshop.
    I am now shooting with my 2nd home brewed batch of emulsion. I tried slowing down the injection of the silver nitrate. No noticeable speed increase.

    Please keep me informed if there is an advanced class next year. Thanks.
