Thanks very much for that Jason...excellent description
Bringing up the old HDR chestnut there was talk of using pairs of frames for HDR. I think Stuart English said it could be done whilst RED was controlled by laptop.
Say the frame rate is 30fps. First frames may expose at 1/1000 sec at the end of it's frame and then at the beginning of the second frame, it exposes at 1/100 sec. Now forgetting for a moment how you 'combine' these frames, do you see any problem regarding the sensor characteristics of these two 'takes', i.e pixel well/other transistors i/o tranfer characteristics which may prevent this HDR approach from being feasible?
Also I read a bunch of hardware techniques for getting HDR out of a sensors which involved sampling at different cmos/ccd bias levels. didn't read much into it. don't know if RED could do this with firmware change?
Cheers,
