Calibrate your digital camera for RAW shooting using QPcard 201, Adobe Photoshop and Adobe Camera RAW (ACR).In ACR there is a tab called "Calibrate". Here you will find sliders for adjustment of Shadow Tint, Red, Green and Blue Hue and Saturation. Using these sliders you can finetune the color reproduction of Adobe Camera RAW converter. However, it is almost impossible to succeed without a reference color target like the QPcard 201.
Finetuning of RAW can be achieved manually or automatically. The manual procedure is described by Bruce Fraser here http://www.creativepro.com/story/feature/21351-1.html
In order to accomplish this with QPcard 201 you need a reference image with RGB values. This image can be downloaded here.
But there is also an automatic way to go. Rags Gardner at http://www.rags-int-inc.com has a Technology department on his site: http://www.rags-int-inc.com/PhotoTechStuff/ with lots of useful information and solutions for digital photographers. Rags has written a Javascript for automatic color calibration with ACR. The script can be downloaded free from Rags site here:
