First off, I am SO glad I came across these forums!
I'm an artist (just about to graduate with my BFA), and primarily a painter but I combine photography with my paintings via liquid emulsion and printing photos and painting on top:
The reason I'm so happy to have found these forums is because I was previously using Kentmere VC liquid emulsion, but it was recently discontinued and I'm scrambling for a replacement. I bought Liquid Light in too much of a hurry and I am have none of the luck I was getting with Kentmere. So I'm looking into other brands and possibly down the road making my own emulsion.
Anyhow, I'm an exhibiting artist, and if you're interested in seeing more of my photo-based paintings, click this: http://www.kellymckernan.com. It'll be a nice treat to hear feedback from people who actually understand the process!
