P3D Re: 3D of a 3D audience viewing a 3D projection

Well,  do you have a regular camera with a built in meter that can tell you 
how many 
stops of light you will lose by  putting those glasses over your camera lens? 
 I think you will have to take several readings with a light meter of the 
different areas of your 
proposed photograph and decide which area is most important in getting the 
correct 
exposure and expose for that area.  If you put the audience far enough away 
from the screen a little directional lighting shouldn't interfere with it, I 
wouldn't think.  A flashlight turned on in a dark room hardly lights up the 
whole room. Maybe a background light would work--one low to the ground set 
near the audience. I would take this photo with a regular 35 set on manual 
exposure control first and just try 
different things first.  Or maybe you could just use a flashlight laying on 
the floor near 
the audience.  The light would be reddish, so you could try putting a green 
sheer scarf over it to change the color of the light.  Not too sure about the 
color balance here.  I think it is green that balances out red.  You will 
definitely need to adjust your exposure from the readings to 
make up for the loss of light those glasses will cause.  Good luck.
