 |

Somebody claimed that the colour space setting even impacts the RAW data
on some cameras, because the gains of the amplifiers of the invidivual
colour channels apparently are different under different colour space
settings. Is this true and for which cameras does this hold ?

Untrue.
I think "somebody" is confusing this with white balance,
which can on some cameras change the raw data for that very
reason.
My Pentax *istDS scales the channels according to WB before
saving the raw data, but the newer K10D for example does
not. It's of little consequence unless the camera WB is set
wildly different from reality, in which case some channel
clipping can occur prematurely.
Probably the commonest example is tungsten light with the
camera set to "shade", which easily clips the red channel
unless you're very careful with the exposure.
