Hey guys... I just called 9:30, spoke with a great staff member who checked into this, and apparently they're allowing point-and-shoot cameras only for the show. So, no professional photographers and, according to what I was told, no cameras with lenses that detach. Odd, but at least they're allowing some cameras
And, there was nothing specific mentioned about whether a flash couldn't be used, but I'd be careful and ask before you shoot using a flash.
Thanks,
Ally
