If a print "enhanced" for projection on a huge screen simply means printing it lighter to compensate for low screen luminance, it really won't look good. Reducing the printer exposure will make the shadow areas less dense and "milky", make the colors desaturate, make the flesh tones pasty, and lose highlight detail. The largest lamp practicable for 35mm is 7000 watts. Size the image to obtain proper screen luminance (at least 12 footlamberts), and don't count on a lighter print to allow a lower luminance and look good. I agree that a 5-perf 70mm blow-up would be much better suited to filling a huge screen, as Gordon has done on numerous occasions at the Cinesphere IMAX theatre at Ontario Place in Toronto. ------------------ John P.
