I really can't recall the photographer I am thinking of. It might be Kimberly Austin, she mixes all her own emulsions by hand (for van dyke, cyanotype, gum bichromate)... I just don't think it was her that I had met a few years ago.<br>
<br>I also thought of the photo center in the east bay, is it Hayward? IIRC, they do a lot of teaching there and had previously focused on film/darkroom & alt-process developing. I think it is in a community center or some similar site.<br>

<br>
Maybe it's not a good way to go for bromine in particular, but any<br>
idea if we can use our non-profit status to get better chem sources? I<br>
know we've discussed institutional suppliers in the past.<br>
