Controlling Color: Hue Adjustment
This option is used to adjust the hue of photo-
graphs as they are taken. Hue can be adjusted in
the range –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.

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.
