thanks for the hint, I checked it. Now I am in the topic.

I found somebody who gives the sRGB values of the colors on the color
control patches I photographed, that means I can calibrate the
photographed color control patch colors all together to the "one" the
"right" sRGB combinations, right? meaning all the color control ptches
in all my pictures will show exactly the same colors?

I found some approaches of histogram warping. I would try the
following: cutting the photographed color control poatches, size them
equally, then I would calculate the transformation, it would be
different for each image.

I found some papers from the mid 90ies to early 2000s discussing the
best way to warp images, linear vs non-linear models. May be this is
already integrated in a IDL procedure or function?

then: can I apply the transformations calculated for the color control
patches to the rest of the images? (I would have to, right?)

Thanks in advance (from the non image processor and non programmer)
Tom
