Thanks for the replies. It is interesting to hear such varied experiences. I'm going to do a simple test.
Light a closeup for RED ONE at 500 ISO on my meter- lighting it with contrast ratios as I would for film, which would look good to eye as well. Specifically, I will probably put caucasian skin tone keyed with a side or 3/4 frontlight reflected at a 2.8 2/3 or 4.0, fill at a 1.0 1/2 and some edge lights measuring with an incident meter at 2.8 or 2.0. I'll set the lens to a 2.8. I'll look at the image at camera ISO 320 and 500 in REC709 on Build 20 and examine the false color and report the results. I'll also post process the image these ways in RedAlert and try to dial in a curve to make the image look good.
If the camera were behaving like a 500 ISO medium one would expect the skin tone to look "normally exposed" or at the very least 40 IRE. If anyone has done anything similar I'd be interested to know your findings. From my previous testing I would think this image would be very underexposed and need to be brought up a lot in post processing, resulting in a lot of noise. But I want to at least give it a shot...
Interesting test- when have completed it I'd be interested in seeing the results if you do nto mind posting the images.
