Does anyone understand what are the mechanics behind the ISO settings
for RAW images?

Yes, I understand them. At least for the Canon 1D Mark II: there are
three buttons, a finger wheel, and a thumb wheel. Maybe the Nikon D70s
has the Telepathic Adaptor which can lock onto the mind of the
photographer, thus dispensing with these crude mechanical implements?


I think the poster was asking a more generalized question than you
responded to, but hey, who am I to stop you from making a jerk of
yourself.

Usually the lowest ISO setting of your digital camera is going to be
where you get the best picture with the lowest noise. Higher settings
are amplified, I believe, so noise is increased.

They are only in increments of 100, 200, 400 to remain reciprocal with
shutter speed and aperture settings.
