Not very much in a single scene, but we use a lot of clever dynamic contrast tricks to perceive more.
I was saying before that if the software allowed for white balance with a pink filter you could improve the S/N ratio.
But you can go the other way, if you shoot through a light greenish filter and re-do the white balance and the use DRX you can get two or three stops more highlight detail.
Canon seems to "flat top" the chroma without too much damage and they seem to be doing their version of DRX, so with enough low pass on the chroma to make up for the extra red and blue noise, and working the DRX harder you should be able to get in effect two more stops by using a greenish filter and re-doing the white clip points.
The odd thing about using a pink filter to bring the red/blue white clip in line with the green white clip is that you loose the advantage of DRX, so while the S/N goes up the dynamic range goes down.
Kodak sensors like the one used in the Acam dII seem to have a wider green bias than some of the other brands of sensor I have looked at the true RAW data from, so maybe Kodak thinks people will use DRX like highlight recovery all the time?
15.5? Yeah baby!!! YEAH!!!
Jim, a few questions if you may. Does 13.5 come from a 2k down-conversion? Are you still pushing ahead on M-X? Think you can get an other hair out of it?
