Hi all,
we're going to use a similar scanning back (Betterlight Super6k) on a
research lab to photograph works of art (paintings and sculptures, mostly),
using hi-frequency fluorescent lighting; does anyone have any
experience/comments on the use of Pictographics' inCamera Professional or
ColorEyes' 20/20 profiling packages with this kind of camera / setup? Or
any suggestions for another profiling software that should work best for this?
Thanks in advance,
Paulo Baptista

Hello,
I have been shooting a series of oil crayon drawings using a Betterlight 6K2
scan back. I have profiled the scan back for the specific lighting set-up
using a Colorchecker DC (which I reference myself using a Spectroscan) and
ProfileMaker Pro 3.5.
I find that after I scan the originals and apply the profile in PS 6.0 the
images still require some degree of tonal correction, usually small
adjustments to the black and white points. Generally, I would convert to my
working RGB space (Adobe RGB 1998) before making the above mentioned tonal
corrections; however, for this particular series of drawings, I am getting
much better results (contrast and color) by making the basic tonal
corrections while in the RGB space defined by the scan back's profile and
THEN converting to my working RGB space for any other corrections that may
be required.
Does this defy conventional wisdom?
Thanks,
Jim Morris
