If you set your white balance with the neutral gray target, you can use the ColorChecker Passport patches to do
a quick check to confirm proper color, and the clipping patches to fine-tune highlights and shadows.
1. Sample the black patch with the eyedropper. This patch should be nearly neutral, so the R, G and B values
should be close to equal. Although the black patch is very dark, it should not read as pure black.
2. Do the same thing with the white point. The white square should be very light, but not pure white; and the RGB
values should be nearly equal.
3. To check the color cast, select the gray patches in the middle. Red, green and blue values should not vary from
each other more than seven points on a 0-255 scale, or three points on a 0-100% scale.
