Thanks for the posts.
I used to go to Siggraph and NAB every year, then quit going to Siggraph when it got to be mostly students looking for jobs.
That said, I’ve not been to Siggraph in about 5 years, and will probably go to Siggraph over NAB this year. I’m pretty set on camera gear and other hardware. I do have some 3D and compositing app questions and Siggraph might be the better venue.
