HDR: The Great, the Okay, and the Yikes!

Of all of the picture improvements being discussed today, high dynamic range (HDR) offers the most bang for the bit. It has other characteristics that could also be described as “great.” Implementation will take some work, which is okay.

Correction:  About 35:30 in, the term “ground glass” is used for what test viewers looked at during projector-illuminated tests.  Actually, it was an LCD screen being rear-illuminated by the projector.

Elucidation:  At about 26:24 in, the chart says “Peak Brightness;” as “brightness” is a perceptual term, the original chart should have been labeled “Peak Luminance.”  Since the black level was fixed, the increased luminance did indicate increased dynamic range.
