Highest usable ISO on RED Scarlet

[Brandon J.F.]

This info is good and what I've been looking for. So given the consensus is anywhere from 320-500ISO for a clean image, and 800ISO ok too and even as high up as 1600... how would one go about shooting with streetlight lamp lighting in the neighbourhood of 6400ISO @ f2.8?

ISO 6400 @ f2.2 with streetlight lamp lighting. It was just a quick test...

This is a pretty heavily treated ISO 4000 image from the Epic.
the Scarlet should be kinda similar.

I don't go above 1250 unless I'm prepared to de-noise in post.

That's my personal limit.

Yup 1250 is my limit as well

Don't forget to black balance your cameras either......

ISO 5000 + 2x really crummy tungsten desk lights. Denoise was at 4, sharpness 1.

I wanted to get a nice gritty look, so it's usable in the sense that it gave me what I was looking for.

EDIT: The downsizing has done wonders for the noise, at 4k it's much grittier.

ISO 12800 is certainly usable once processed with some noise reduction.

I hit 1250 and 1600 often and do a bit of NR. I personally try not to go past ISO 6400 for most work. Typically I'm shooting between 320-800 99% of the time.

This particular shot from The World After was shot after last light (sun already over the horizon) and was ISO 1600. A bit of NR and has a good amount of micro detail with what I describe as a heavy grade. No "jumpies" when projected at 4K either.
