I used a lens last week that creates rather flat looking images with some rather pronounced colour shifts. Of course, I can fix that in postprocessing based on a grey card and using curves, but that's rather tedious and not very accurate (read: I'm lost, can't get good looking results).
Now, it would be great if I could create a custom input colour profile that already . I found software (lprof) that can create a colour profile based on images shot from an IT8 reference target. I know you can buy these but darned they are expensive!
Now, since I've got quite a good and calibrated printer setup, I thought it should be possible to actually print the IT8 reference myself. I can't find any synthesized and printable IT8 JPEG or TIF files though. Anyone have one that (s)he is willing to share?
