Understanding Gamma Correction

Understanding Gamma Correction
Gamma correction is the non-linear operation that compensates for the non-linearity
of camera systems and our eye's perception of an image. Historically, CRTs had a

the gamma in order to achieve balance from display to display. Each of our gray
balance settings correspond to a specific gamma value. The table below lists these
values.

Understanding Color Temperature

Different "pure white" light sources do not always have the same color. For instance,
light from an incandescent bulb has more yellow than light from direct sunlight.
"Color Temperature" is a way of measuring these color differences. In general, higher
color temperature numbers are bluer or "cooler. " You may have a reason for wanting
your display to be a specific color temperature. For instance, if you are using the
