• 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 (5500K, 6500K, 7500K or 9300K) mode from the Color
Temp menu (with the Q-1500d, 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 in
“Simple” mode.
