David,
I'm not sure on your second question regaridng Keystoning, but am
sitting here at 6:30 in the morning trying to work out the
optics...good mental exercise.
As for xenon vs. tungsten prints, without looking at any figures I'd
guess tungsten prints are more prevalent. Filmmakers who are concerned
with tone tend to have 2 sets of prints, one for each lamp. I'm not
going to speak for Canyon, but I know that I was once asked by Dominic
if the print I was getting would be shown on a xenon or tungsten
projector.
The Ann Arbor film festival, for example clearly states on their
website that if you choose to send a 16mm print for preview it will be
watched on tungsten, and the festival will be presented on xenon...
I'll note here that it is possible to get a xenon pageant, and I
suspect many other tungsten projectors could be converted.
If anyone has more concrete information, please share...
