“To camera people like ourselves, the term Auto White Balance usually brings to mind that little AWB button on many camera systems. When you press the button, the camera tries to adjust its RGB gain levels to make white things in your picture actually white. However, this is not the only place on set where white values are important. A properly calibrated monitor is essential to ensuring what you see on set is what you’ll actually get back in post. You’ve all probably heard of the basic method of adjusting monitors with SMPTE bars, but that method does not address the most important aspect of your monitor – its white point. The vast majority of monitors and televisions today conform to the Rec. 709 (ITU-R BT.709) standard, which specifies a white point for monitors at D65 or 6500 Kelvin. Below is a chromaticity diagram, which shows the Rec.709 gamut (the black triangle), and in the center you will see D65, the white point.”
