Fig. 11.11 In the telephoto shot on the left , atmospheric perspective has signifi cantly reduced
color saturation and shifted all colors towards blue . On right , a close up of the same type of trees,

literally impossible to distinguish between one color and another, even between two
colors that are exactly opposite, like red and green. Instead, everything in such a
scene will take on the colors of whatever ambient light is present, with details dis-
tinguishable only by tonal differences.
This is important to know if you are taking reference photos from a long dis-
tance, like of a building façade with a long zoom lens. Even if you can zoom in close
enough to fi ll your frame with the building, your camera is no closer to the object,
and the atmospheric interference will still be present and will affect your colors.
A picture taken this way will not contain usable color information, though it may
have good structural information.

Refl ected Light
Refl ected, or bounce , light, is light and color bounced from one object to another
(Fig. 11.12 ). Bounce light does not require a highly refl ective surface like glass or
polished metal. Almost anything will bounce or receive bounced light, even a furry
teddy bear. Therefore, in any scene, you will have colors from neighboring objects
bouncing from one to the other. If you put an orange pail beside a black teddy bear,
