use a yellow filter in a certain combination and in all the illustrations here sits this yellow filter.

yellow sheet of
glass or
plastic-like material placed in front of or behind a camera lens to
control the
transmission of specific colors of light onto the film. Although light appears to be white, it is actually a combination of
different colors. These colors can be
broken down into three "
main" colors--
red,
green and blue. When these three colors are added together, they make white light. When one of these colors is taken away, the two remaining colors combined make a
different color than white. For
example,
red and
green combined together make
yellow; and
red and blue combined together make magenta (a purplish
color). A yellow filter looks
yellow to the eye because it allows
red and
green light to
pass through it freely which is perceived as
yellow. It transmits
red and
green but it
holds back (or absorbs) blue light. For this
reason it creates certain effects when used on a camera lens. When used to take a black and white photo, for
example, a yellow filter will make the sky appear darker. This is because the yellow filter is preventing the "blue" light of the sky from
reaching the film. The clouds will also be more visible because the blue of the sky surrounding them is "held back" and thus the clouds stand out against the darker sky. When used to take a
color photograph, the yellow filter (which
holds back blue light)
acts to "correct" too much blue. For
example, if there is a
lot of blue in what is being
shot, such as when
shooting a
painting where blue is very prominent, a yellow filter will
tone down (correct) the blue. I-nobody has bothered to tell me why they
