[Frameworks] Xenon projection

[Scott Dorsey]

If a film has been timed for xenon or arc projection, it will look a little
bit yellow when shown on an incandescent classroom projector, but the eye
will adjust in a minute or two.

You could put a filter on, but you'd lose most of a stop of light, and you
would lose some sharpness, and in the end the eye would adjust in a minute
or two anyway.

If you're worried about it, dim the room lighting or use orange house lights
before showing, so that people's eyes are already adapted to very warm light, 
and then when the film comes up it will seem artificially blue at first, even.
