Controlling Color: Hue Adjustment
Hue can be adjusted in the range about –9
°
to 9
°
in increments of 3
°
. If red
is taken as the starting color, raising hue above 0
°
(the default setting) would
introduce a yellow cast, making colors that would be red at a setting of 0
°
appear increasingly orange. Lowering hue below 0
°
would introduce a blue
cast, making colors that would be red at a setting of 0
°
appear increasingly
purple.
To choose a hue adjustment, highlight Hue Ad-
justment in the shooting menu and press the
multi selector to the right.

Hue
The RGB color model used in digital photographs reproduces colors using differing
amounts of red, green, and blue light. By mixing two colors of light, a variety of differ-
ent colors can be produced. For example, red combined with a small amount of green
light produces orange. If red and green are mixed in equal amounts, yellow results,
while a smaller amount of red produces a yellow green. Mixing different amounts of
red and blue light produces colors ranging from a reddish purple through purple to
navy, while mixing different amounts of green and blue light produces colors ranging
from emerald to turquoise. (Adding a third color of light results in lighter hues; if all
three mixed in equal amounts, the results range from white through gray.) When this
progression of hues is arranged in a circle, the result is known as a color wheel.
