Scanner drivers certainly differ as much as RAW converters.
No, it doesn't.
The Illuminant is fixed. The dynamic range of fixed. The item being
scanned has a fixed gamut (cameras don't). The film or print being
scanned CAN be also created as a target for the profile process. You
can't do this with a target for a digital camera as is being
discussed (at least ONE target that describes everything you'll
place in front of the camera). Scanners can and should be put into a
default and ideal condition for building the profile (a scanner that
produces an auto correction behavior can't be profiled, you're
chasing your tail).
That you find a scanner and a digital capture device that produce
essentially a single channel grayscale document that's scene
referred anything approaching what a scanner captures (which is
output referred), leads me to believe you have more reading to do.
For the benefit of readers for whom English is not their first
language, I'd like to point out that Andrew has become argumentative
to the point of incoherence -- even to an "English scientist" like
myself.
The more I read, the more I became concerned that I was developing
dyslexia. It was a blessed relief to see his signature at end of it
otherwise I'd have wasted the afternoon on the phone to NHS Direct.
The mention of scanners in that jumble of words leads me to ask if
there is no area of image creation in which he is not an expert?
I've heard tell (but NDAs &c forbid me to divulge the details) that he
is about to release a white paper on the complex subject of egg
sucking... my grandmother is very keen to review it.
Being more of a fan of the cursed PMT, my only CCD scanner is
Scanview's noisy F10. The F10 will give you RAW high-bit data if you
like your images linear. Do other CCD scanners do that -- or is the
F10 unusual in this respect?
