Please, enlighten me.
I recall that discussion, one in which I participated vigorously at first
then tired of because of all the experts who were preaching that it did not
work, could not work, would not work, not one would tell me that they had
tried the ColorEyes 20/20 product. Moreover, none of them as I recall were
real-life working photographers.
All I can tell you is that I have been using this product for several years,
first with Nikon DSLRs, then I switched to Canon DSLRs, and have also used
it with rented medium format backs from PhaseOne, and simply put: "It
Works!". If you properly expose and GRAY BALANCE the target capture, then
properly gray balance in the field, the light source is irrelevant. I shoot
in strobe lit arenas, mercury-vapor, daylight, on-camera flash, you name it.
One profile handles all of this. It seems fairly obvious to me that careful
gray balancing in the field makes colors render the same under a variety of
lighting, but some of the scientific minds seem to want to overanalyze this,
IMHO.
I understand that many on this list want to understand the science and
theory parts of this, but all I care about is that it saves me hours and
hours of editing. I do understand enough to know that the custom target was
carefully developed with only digital cameras in mind. It makes no pretext
of being a scanner target, etc. Also, they guys at Integrated Color worked
long and hard with the folks as ICS to make the software do what it needs to
do.
