I've been able to create a relatively accurate profile for my flatbed with
a Kodak Q60R1 IT8, but I would appreciate knowing a bit more about the lCMS
scanner profiler's parameter's tweeks. Is there a FAQ or description of the
cheerios ... shAf :o)

There is actually almost no documentation, just because this
is a preliminary release. There is some help as tooltips in the
profiler, and here are some additional clues. It is expected full
documentation when the release of the printer profile. Hopefully
in a near future.
"Resolution (CLUT points)" - This is compromise quality/size. On more
points bigger files and more precission. 16 points would be enough for
normal usage. 33 point is the theorical limit, more points would result in
bigger files with no quality gain.
"Strategy" - This is the internal strategy used by profiler to compute the
profile tables. Set this one to "Global". Local analyse does give slightly
better results in a very few cases, but generally results in bad profiles.
We are seriously thinking on to remove this option on next revisions.
"Prelinearization" This is the degree on "smothness" to be applied to
curves. Smooth curves are more pleasing to eye and does minimize
noise and target error. Leave untouched for normal usage.
"Chormatic adaptation" - This is the CIECAM97 model, that can
be used to emulate viewing condition and other wonders. For example,
it can be used to profile a camera translating colors from outdoors
to pich dark interiors. CIECAM97 per se is worth of a whole book,
however you can find some explanation of it on
