Abstract: This article outlines basic photography principles.
The parts of a camera are discussed including the shutter speeds and f-stop
settings. Types of film, lenses, and the use of a flash are also explained.
The shutter speed indicates how much light enters the camera. High shutter
speeds limit the motion that can be photographed because the image will
blur. The F-stop number determines the size of the hole that allows the
light in. This controls the volume of light, which affects the depth of
The film speed is a measurement of the filmís sensitivity to light.
A high speed film requires less light. The drawback to high speed film is
that its detail is not as sharp as low speed film. The photographer must
make decisions concerning what film speed to use. The requirements of the
photograph will often dictate the choice.
The focal length of a lens indicates the angle of view and how much distortion
will result. As the focal length decreases, the angle of view becomes wider.
As the focal length becomes shorter, the angle of view is narrower and the

The flash adds light to the scene of the photograph. This article also
