Using A Color Checker Chart
Color reproduction, loading color profiles and calibrating monitors & printers can become an endless tangled mess that leads to frustrating headaches. Proper use of a color chart can get you a lot closer to actual colors and save you a lot of time dialing in your post production work by adding a simple step to your workflow. A couple years back I pickup the X-Rite ColorChecker Card and by doing so I have saved a ton of post processing time. During each and every shoot I take one frame before we begin, as a measure of the light temperature and proper exposure with a color checker chart.
