Surveillance

A photo of angry Ms. Hall

Shutter Definitions

1. Shutter: a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as in a movie projector or signal lamp.
2. Shutter Speeds: the time that the shutter remains open when taking a photograph [1/1000 s, 1/500 s, 1/250 s, 1/125 s, 1/60 s, 1/30 s, 1/15 s, 1/8 s, 1/4 s, 1/2 s, 1 s ]
3. Shutter Priority: a setting on some cameras that allows the user to choose a specific shutter speed while the camera adjusts the aperture to ensure correct exposure.
4. Exposure & how to set your camera for a good exposure: the total amount of light allowed to fall on the photographic medium (photographic film or image sensor) during the process of taking a photograph
5. Bulb: abbreviated B, is a shutter speed setting on an adjustable camera that allows for long exposure times under the direct control of the photographer
6. Cable Release: a device consisting of a flexible wire that is pressed at one end to trip a shutter mechanism on a camera.
7. Tripod: a word generally used to refer to a three-legged object, generally one used as a platform of some sort, and comes from the Greek tripous, meaning "three feet".
8. Light Meter: a device used to measure the amount of light
9. Bracketing: the general technique of taking several shots of the same subject using different or the same camera settings.
10. Hot Shoe: shaped somewhat like an inverted, squared-off "U" of metal

Camera Vocabulary

SLR - A single-lens reflex (SLR) camera. This is a camera that typically uses a semi-automatic moving mirror system that permits the photographer to see exactly what will be captured by the film or digital imaging system (after a very small delay).

TLR - A twin-lens reflex camera (TLR). It’s a type of camera with two objective lenses of the same focal length.

Lens - a transparent optical device used to converge or diverge transmitted light and to form images

Shutter - a mechanical device on a camera that opens and closes to control the time of a photographic exposure

Shutter speed control - common term used to discuss exposure time, the effective length of time a camera's shutter is open.

Aperture – a device that controls amount of light admitted

ASA/ISO - Speed rating for photographic materials devised by the American Standards Association.

Shutter Button - a button found on many cameras, used to take a picture. When pressed, the shutter of the camera is "released", so that it opens to capture a picture, and then closes, allowing an exposure time as determined by the shutter speed setting

Rewind Knob -  this is usually rest around pentaprism of the camera. It has an electrical contact which mated with a contact in the mounting foot of the flash unit.
