Ok explain this one to me... I set up a shot to shoot Gov. Jeb Bush at a podium. They have a video projector shooting through his head and projecting in the back of him. I estimated how tall he was, (Jeb is about 6' something) and put one light at an angle as to not blow out the screen. I put a dichroic filter on the light to balance with the natural blueness of the projection. The lights were all out so I didn't have to worry about any tungsten spill. When I got it back his face looked perfect but the projection was green.
What the hell went wrong? The natural color of most monitors or projectors is blue. I have always shot them on a 3 filter. As a matter of fact when I shoot a computer I will pull up a page on the computer with white on it and balance on that. If I get a wide shot of the computer itself I will throw a blue light on it.
But what happened. Do some projectors emit a megenta color? (That's just a guess... i don't know what the oposite of green is).
