PHOTOGRAPHY One of the first cameras invented was called a camera
obscura. Light entered an opening in
the front, and an image was reflected
in the back of the camera, upside down,
forming similayotriangles. If the image
of the person on the back of the camera
is 12 inches, the distance from the
opening to the person is 7 feet, and
the camera itself is 15 inches long,
how tall is the person being
photographed?
