• Color Temp: Select Color Temp from the Display Color - Common Settings menu to

adjust the color temperature. Color temperature establishes the “color of gray” by

adjusting the 75% white point to various color points.

What are “color points?” A “color point” is an x/y coordinate pair that defines a

color’s location on the standard CIE chromaticity graph, shown in Figure 4-7. (CIE

stands for “Commission Internationale de l’Éclairage” (International Commission on

Illumination), the organization responsible for color measurement and management

standards.)

• Simple: Select Simple mode from the Color Temp menu (with the Q-750d Ultra, this

is the only choice) to choose one of four color temperature presets: 5500K, 6500K,

7500K and 9300K. The default setting, 6500K, is appropriate for most situations.

Higher settings produce a “bluer” picture; lower ones impart a reddish hue to the

image.

Table 4-2 lists the x- and y-coordinates for each color temperature preset.
