Can you treat the Red like a film stock?

I have my first short project on the Red Camera. I've worked with it as a assistant on some small music videos so I understand the menus and what not. I was wondering if you can treat the 320 ASA as a film stock? Meaning is it bad for the sensor to rate it 1/3 slower?

I've worked with some DPs that rate it at a 250 just like they would with a film stock for better blacks. I've also heard of people rating it faster to combat against over exposing the sensor. Since I usually rate film 1/3 slower it would be nice to do the same with the Red. My concern is can that put the sensor in danger zone with highlights?

1/3 of a stop -- from 320 down to 250 ASA -- is pretty minor, within a margin of error in exposing. I wouldn't worry about it. I actually think the RED needs more exposure anyway and is closer to 250 ASA if you want to keep the noise in the shadows down.

Actually I've worked with a couple of DPs that rate it a stop or a stop and a half faster. I heard that it's better to underexpose a bit when working with RED-- not only to save the highlights (since it's still video after all), but RED raw footage has 11 stops of latitude-- so you can always tweak the exposure a decent amount in post. I guess it really depends on the DP, and how much of the image will be manipulated in post.

My experience with the RED was that the noise from underexposure in tungsten light was more annoying than the clipping from slight overexposure, but that's partly a matter of taste. I rated the RED at 640 and 800 ASA for some night exterior work due to necessity and it worked OK but it definitely had some blue channel noise issues.
