José, thanks for the tip about Jose Pereira's website. There are many fine resources there, and an opportunity to improve my spanish! I'll give his profiler a try. Paul Schilliger
From: José Ángel Bueno García Targets may be updated (purchased a new one) every few years, depends on the use and manipulation. I really don't know nothing about camera calibration since data from profiling applications don't remain in the camera but in the profiles folder, and you need shot in raw and workflow where camera profiles can be used. I assume you know.
Don't know other than Adobe Photoshop/Lightroom with ColorChecker. If you own any other target can make use of ACR Calibration Scritp that "acts" on camera profiles in the Calibration tab. Have never known if acts on RIMM or ROMM. roughProfiler (ArgyllCMS based wrapper from Jose Pereira) supports HCT and in his site you can find other usefull tools. PictoColor's inCamera Photoshop plug-in works with HCT too. I really don't know if you are going to get a dE value less than 2.8 CIEDE2000.
