Screen Luminance for Drive-In Theatres is specified by SMPTE Recommended Practice RP 12-1997. Ideally, it should be 16 footlamberts +/- 2 footlamberts. Recognizing the challenge of lighting a huge outdoor screen, "when maximum compromise must be made", it should be no less than 4.5 footlamberts. In general, use as much power as you can get. I recall burning 11 mm rotating carbons at 120 amperes and 65 volts, or about 7800 watts, to light a 100 x 42 foot screen. A "cold mirror" and water-cooled jaws and gate were mandatory. I remember the effect of rain or moisture on the screen was like a "gain" surface. If the moisture was coated evenly, the luminance was brighter than on a dry screen. Usually, the rain caused uneven streaks, however. Projecting on a foggy night was an experience! Likewise thunderstorms! Rats were a constant problem on the lot (discarded food), and occasionally in the booth. ------------------ John P.

The Roanoke Times, the local paper in our area, had an article on the front page of the Entertainment section today about the Hull Drive-In. It had a picture from the inside the booth of Jim Boyd and one of the projectors. You don't see that on the front page of a newspaper section too often. You can read the article at: http://www.roanoke.com/roatimes/news/story94962.html Unfortunately they didn't post the picture too  ------------------ Colin Wiseley Lyric Theatre Blacksburg, VA www.thelyric.com
