Scott, you remember that stealth picture I posted awhile back of the Technicolor DLP, right? Maybe Brad can find it and repost it here.

I don't know about the QuVis being orange, but here is the Technicolor projector picture from an earlier discussion.

The film print I watched at the AMC Empire that night was in reasonably good shape (a few minor vertical base scratches and some dirt particles --- easier to see in the white "snow" scenes). From my seat 2 screen heights away from the screen, the image was slightly soft, likely due to the rendering/recording at only 2K or less. IMHO, the trailers projected by the DLP before they shut it down for the "hiccups" were NOT better for sharpness at that viewing distance, and did have the same annoying DLP-Cinema tone scale issues I've commented on before. I've learned not to sit much closer than 2 screen heights for today's Digital Cinema presentations to minimize seeing the "jaggies" and pixel structure.

John,

Are you positive that you were EXACTLY two screen heights away from the screen? You could have been off by a millimeter or two, which I think you would agree will destroy the entire presentation. The only way to do this properly would bring your tape measure to the show and measure the screen height, masking to masking making sure that your tape measure is perfectly vertical. Then you must double that and sit that far back from the screen ignoring stadium rising or slope of the auditorium. In other words, you can't just start the tape measure where the floor meets the screen wall and go back two screen heights. You must be able to sit and hold the tape measure perfectly horizontal from your eyeballs to the screen.

I also amaze people by accurately measuring screen luminance to within a footlambert "by eyeball", without a properly calibrated screen luminance meter --- NOT!

Actually, estimating viewing distance is not that difficult.

Architectural features called ceiling tiles help a lot! They're typically 2x2 or 2x4.

Yes, but sometimes the screen will be an additional 1/32 of a ceiling tile in. And you MUST know how tall the screen is masking to masking. Remember, it must be exact to the millimeter or you might as well leave. What if someone is in the prime pole position seat you are required to sit in?

Joe asked: "What if someone is in the prime pole position seat you are required to sit in?"

I politely ask them to move.

Actually, I always try to arrive early enough to have a choice of seats.
