You are lucky. You have the Sinar. The Sinarback calibration is VERY good at
getting the color close if not 'perfect'. This avoids some 3rd party
profiling issues / problems. For me the 240 patch works much better than
the 24 for the Captureshop calibration.
Camera profiles built with Gretag and others have also worked well but only
for the single setup for which the profile was made. These profiling
packages sometimes prefer the 24 patch target, depending on moon phase. The
trick to using some 3rd party profiling apps is that your original captures
(targets and scenes) should use a linear curve. Build the profile from the
linear target export then assign that profile to the linear captures of the
scene. All that profile building and and assigning can be batch applied in
post production. Meanwhile, back at your camera monitor with the art
director, use one of the standard curves so it doesn't look so flat on
screen while shooting.
Lately we just use the Captureshop calibration, 240 patch target and a 1.8
gamma Captureshop / Photoshop working space like Bruce with gamma adjusted
to 1.8. We stay in this 'perceptually uniform' input space until final CMYK
conversion. Input banding issues have since disappeared.
The modified Bruce 1.8 often delivers better reds and oranges than
ColorMatch or Apple RGB. This might help your wood furniture.

Hi ....
I4ve got a little problem....
I have made one Icc profile of 1 digital camera (Sinar 23). To do that I
measured the light Temperature (5020:k) and other conditions to make sure
that
all was being ok.
After calibrate the camera, we did the photo to the ColorChecer card of
Gretag
(240 patchs). After that, I made the Icc profile with the ProfileMaker.
With
the same conditions of light etc ... exactly the sames, we did another
photo
to some types of woods (we works with furnitures).
Ok, as far as this moment all was going ok but...... when I put the new Icc
into Photoshop (with calibrated monitor ofcourse) like source RGB Icc the
resoult was very bad. It seems another wood... :o(
I have seen the Gamut, and aparently is ok.....
Could somebody help me to found the reason of that????
Thanks in advance...
