Jim,
Thanks. Don't let the craziness consume you.

That was my instinct, has anyone tested the two methods side by side with results we can reference? I'd like to see this "bloom" effect on the rolloffs vs RAW in a motion clip.
About the low-con filter idea. Can it be user installed or switched out? The option sounds great to have it or not.
As long as the raw acquisition concept without processing, only compressed applies- which is the core of the RED image acquisition philosophy ISO influence on the DR remains.. just like pulling or pushing film stock...Well, RED implied that ISO was changed in Dragon. MX ISO *does* affect dynamic range. RED suggested that Dragon would be different somehow.

When RED announces they are processing the image before recording (i.e. apply gain) it will change...
So you get the same 16+ stops of latitude at 200 asa as you do at 2000 with the Dragon. No latitude penalty when you lower ASA. Which means when you are shooting outside, less ND filters. Less IR issues, better images.
The Dragon has more native dynamic range than any motion capture camera ever made as measured by the standard engineering definition… signal to noise ratio. And it does it with the least amount of noise.
Hi Jim,
what is RED's methodology for measuring S/N?
There is a TV engineering standard for electronic cameras, which for 20 years has and still is very accurate when comparing cameras between manufacturers.
I'm told its done with a with a calibrated light box at 3200K 2000 lux S/N is measured with a Shibasoku s/n meter with gamma off and 20mV black level.
I was impressed in the early days when you quoted a S/N for RED when the others declined.
What is the industry accepted engineering standard for measuring S/N on a D cinema camera, surely it is not the above method using a HDSDI output but an agreed way of measuring a raw file?

Unfortunately, many manufacturers use a different methodology measuring S/N. The best bet is to have a single independent 3rd party do it and reference all cameras to the same methodology. We are in the process of doing just that.
