There are number of us LF / ULF users in the LA area that get together occasionally. Hugo Zhang puts on the Chamonix Shoot-Outs every once in a while so keep an eye out for them. The last was about a month ago in Orange County where we did a morning of figure shooting. If you want to get something going with the "big camera people", just put a notice proposing a time/place and we'll start coming out of the woodwork. You can also check out things over on the Large Format Forum as well. Even if you don't shoot Large Format, you're still welcome - maybe we can covert you.
