Re: Capture NX and UniWB problems (D200)

Thanks Julia.

One additional question:

Where does ISO come into the picture? The recent thread with the underexposure tests had me somewhat confused, since they perhaps indicated that one could underexpose one stop instead of turning up ISO. However the histogram is (of course) clearly affected by ISO speed.

I always thought ISO speed somehow set the gain of the preamplifier(s) to the A/D converter(s) (which is in accordance with what the histogram displays). If this is not the case and the ISO is just a parameter, then different ISO settings would still cause the histogram to lie?
