ISO rating

[alanfocus]

Just wondering how fast Red is?
Arri D20 is slow as hell whereas Panavision Genesis is about 800 ASA (I've shot under sodium vapour street lights with +.5 gain and it worked).
So where does RED come and how much control do we have.

Howdy,

With over 25,000 posts on reduser since January - I'd recommend the search function for basic questions.

Here's one of several posts on the topic:

Welcome to Reduser.net, Alan! Good to have you aboard.

The asa is still an unknown, really, and somewhat affected by the amount of noise visible at lower light levels. We'll know when we start seeing field tests. I expect Steve Gibby will be doing some comprehensive testings in a few weeks, as well as others.

For now, the collected wisdom is that you should count on 320 or higher, but with the potential for fantastic signal to noise ratio at lower levels.

spoke to Jarred yesterday and he said around 320 ISO

He also said you can gain the camera up to 1600 ISO, this will improve with an upgrade possibly..

You can get up to 800 ISO with little grain

Cool, Richard. I have utmost appreciation for our troops on the ground at NAB.

Shock and Awe. Shock and awe.

we meter at 250 right now to protect for highlights... can push it almost two stops up. bumping to 800 is no problem.

Hi Jarred,

How does metering at 250 protect for highlights given your under-rating the chips nascent ISO (given 320ish).

Sounds to me like your "Pulling" 1/2 stop or so IMHO?

the 320 never came from me.. i think richard got that number from someone else in the booth (it was a huge amount of info flying around in there.)

and we arn't pulling, we are pushing from the lows... we can reach really deep into the shadows.

Damnit, I'm sorry.. didn't mean to misquote.. My brain is mushy. I know I'm not crazy though, I heard that 320 # a few times around nab yesterday

OK, so regard of pushing or pulling what are you guys rating the camera at? It's a simple answer really, one that doesn't require pushing or pulling. Get a spot meter rating from a grey card, compare it to what the camera sees...
what do you have?
