I too was a bit disappointed. I got there shortly after the show opened. I went without a mission, nothing particular I wanted, so I was looking for "something wonderful". I bought a couple of filters, a step up ring, and a small Daguerreotype photo in a well worn case. I was there for less than two hours.
It was mostly a film crowd. Yeah mostly old white guys like me (age 58). There was a youngish woman buying up cheap LF lenses for when she teaches wet plate. One or two younger guys selling stuff.
