STEREO photography
Stereo photography is early as
the camera itself with a peak at 1890-1920. in the 1950's stereo photography
revived and stereo home photography was popular. The stereo effect is created by taking two pictures
at once from a stereo camera with 2 lenses or
the
early method of taking 2 pic. form the same camera which is moved
(that
method is not very effective for taking a picture of moving objects like cars, animals etc).
Looking closely at both pictures
the human eye (and the brain) creates a third pic. which is 3-D
the early method
the Stereo-camera method
