Rui, I'm glad you brought this up. I think we need to reacquaint ourselves with these kinds of fundamentals now and then. I take all this knowledge quite seriously, so it's good to be reminded to think about it.

My take on RAW ISO: you have to set your light meter to something. ;-)

It seems that, unlike stills cameras, RED RAW does not 'bake in' your ISO setting. It just records what hits the sensor, and that's it. ProRes is obviously a different thing.

Mark, I look forward to watching your video.
