I have a not so much IDL problem:
I have taken some pictures, some in the morning, some in evening, some
in the sun, some in the shade.
They all contain acolor reference.
Given that all individual images are homogeneous in light (no dark
regions, no lighter regions) there must be a possibility to process
the images in a way, that they all show the same (or nearly the same)
R,G, and B values for the colors on the color reference, right?
Can I find models how to treat the colors of the whole image just by
using the color references?

Thanks for any hint how to start with that problem, I dont find the
entrance to it... :-(
