It was a pleasure to meet Suzanne and get an extended look at some very impressive photos. The series is on her website, and some are on APUG, but the web versions are a poor substitute for the real thing.
I highly recommend stopping by if you can get to Groton, MA.
My daughter and her friend enjoyed the workshop also, and came out of it with sepia Polaroid portraits of them together. Mine will be turned into my avatar here, when I get a chance.
It was fun to watch the crowd looking through the ground glass, many it seemed for the first time. There were a couple of "What am I looking at?"... then a few seconds later, the exhaled, "Oh!!" as they 'saw' it. I think at least a few people came away with some new understanding and insight.
