In that context I think it's appropriate to say that the RED has an EI of 320 with favorable push and pull characteristics, as a film manufacture might put it.

I can't wait to see build 16 because it has been a bit of a game exposing for this sensor, because metered stuff looks "dark", but I know that Jim has stated that all of these problems are resolved in 16.

If you open QT tiff files that I posted links to here in FCP and look at them on the scopes, you'll find that 500 "looks" better, and 320 feels "under". This is why 500asa seems or looks more correct, there is just more signal there.


arrgh: i hope 16 is days and not weeks away
