Mark, you are right, I was probably a little unfair on my opinion. It was mostly targeted at those who tend to "over-credit" the advantages. A discussion like this needs to be realistic and factual.
I haven't lived with a DI projector, the concept and function just don't attract me. The one thing I haven't seen is a mapping of the Iris function. Just when does the iris start to close and how much. Seems like a test with a white window or white field, reducing the level by 1 IRE increments would allow observation and measurement of the iris and gamma modifications. At the point the iris is fully closed, the luminance value should be the threshold for CR measurement. If the luminance value was, say, 1.5%, then, with a full black field, and a 100% white window, area totaling 1.5%, should be the CR measurement point for "MAX DI low APL CR". Does this make sense?
