High-end camera calibration, how do you do it?
« on: September 30, 2013, 09:25:14 am »

I have an interest in camera calibration from a technical perspective and I'd like to know how to perform a high-end camera calibration, for say reproduction photography. I'm assuming that a 24 patch color checker is not used for high-end stuff. I've also heard that checkers do vary a bit in color copy to copy, so one would need a measured one (with a high-end spectrophotometer I guess) and a table with the actual colors to feed into the calibration software. Or maybe everyone's using monochromators rather than color checkers these days?

Is there any pointers/books out there that shows how to do it properly?

We use Color Checker SG charts to originate the profile and the validate the profile using both a Color Checker SG and a ISS Golden Thread test chart which is FADGI Compliant.

Cultural Heritage FADGI Compliance.

The hardest part, by far, is getting a capture of the test target with as little glare as possible as even the slightest glare will ruin the profile. We have some tricks for this which take it from nigh-impossible to just-very-hard.
