I've been asked to look into some projector options for a expanding VFX operation. One of the goals is to have a brightness level at the center viewer/audience position that is about what can be expected in a typical U.S. movie theater. But short of getting my light meter and going to a bunch of movies I'm having difficulty figuring out what that goal brightness should be. So I can't figure out how bright/powerful of a projector would be required for the space. Any information would be helpful on this. Even a push in the right direction to figure it out would be appreciated.
If knowing about the space would help it is going to be 18' wide wall to wall, 15' to the drop ceiling, and 22' from front to back wall, with the problem that the projector can't sit on the other side of the wall. So the throw will be about 19' probably.
Thanks you for any assistance,
