I am attempting to copy paintings and various 2D artworks using polarised flash and a polarising filter on my lens and need a really good camera profile for this exacting work.
The profile I have made using the DNG profile editor looks very weak across all the colours of the test chart and I could never apply this to my images.
Can anyone give advice on how to get a good result? Am I meant to be tweaking colours by eye to best match the colour checker? This would seem a really bad work flow!
I used to be very happy with the Thomas Fors calibrator. . . Cheers, Ian
You test the color accuracy of the profiles you make with scripts from this page:
Or I like to use Imatest Studio which gives a graphical representation of the color error, as illustrated here:
These measure hue error not luminance (brightness) error, and perhaps optimal hue doesn't lead to pleasing images.
You can try starting with a different default camera profile instead of Adobe Standard, maybe Camera Standard, and see if that results in a better profile.
You can compute the values for the RGB Hue/Sat sliders using one of the Rags-Gardner or Tindemans scripts, and then compute the profile with those slider values in effect.
