to All,
This thread has caused the dissappearance of any remaining patience I
have to hold back!
Maybe it is time that this group pay more attention to how
photographers need to be able to work than "science and theory".
It is the task of us who understand the process of profiling to make
it USEFUL and PRACTICAL to all, not baffle them with TECHNO-GARGEN.
the old saying comes to mind................"those who can , do,
those who can't..................
Ill stop my rant now!
Anyone please feel free to conact me offline about this.

> What we need is a clear understanding of what a camera
profile does. It does characterize how a camera responds to a particular set
of colors
under a specific lighting condition.
My recommendation to profile under every situation on the fly doesn't
invalidate that view.
If you change the condition, i.e. shadow one corner
of the target or have one light 100 degrees kelvin cooler than another you
will
radically change the outcome.
That's why having a means to profile that scene somewhat automatically in
the capture software is what we need.
What you need is one
profile created under these carefully controlled circumstances, that can be
applied under
most lighting circumstances following proper linearization(gray balance) of
the camera
> for each scene.
