It controls the length of time a picture is exposed. In film Photography this is a literal "door" that opens and closes allowing light to expose the film for a given amount of time (Example 1/60th, 1/125th of a second). In digital photography the door is not needed, the camera's sensor simply captures light for a given interval and records that as a single picture. This is why digital cameras are so quiet when taking a picture and manufacturers have taken to adding speakers and a "click" sound so people know they have taken a picture. The "click" they are simulating would have been the sound of the shutter opening and closing on a film camera. In motion picture photography or video the shutter speed (or angle for film cameras) refers to the same thing, how long the shutter is open during each frame. Typically 1/48th of a second (or 180 degrees) for film and 1/50th or 1/60th of a second depending on what country your video camera is from. In either case the shutter speed effects how much light is allowed to the capture device or film. The longer the shutter is open, the more light but also the more motion blur. Fast motion such as sports is typically shot at a high shutter speed if the desire is to stop the players in motion. If you want a picture of a football player's legs blurred to show their motion a lower shutter speed will do that.
Simply, the shutter release takes the picture. The shutter release is the button on a camera which, when pressed, "releases" the spring tension on the shutter which "trips" the shutter to open and close and expose the film or sensor to light coming through the lens.
But I wondered if you were actually asking what a cable release does. Most film cameras and some digital cameras have a little threaded port, usually on the shutter release button, into which you can screw a cable release, which is a flexible cable with a spring loaded plunger which when depressed will release or trip the shutter. The flex in the cable allows the shutter to be tripped without moving the camera.
A cable release is used when the camera is solidly mounted on something such as a tripod and allows the photographer to release the shutter without directly touching the camera. This is important when the exposure is long (some photographers prefer to use a tripod and cable release for all exposures, but others consider a "long" exposure to be any shutter speed equal to or longer than the focal length of the lens in use) and "time" exposures running to several seconds or even minutes. The cable release allows the shutter to be held open for long periods without the danger of even slightly moving the camera and blurring the exposure. Some cable releases are equipped with locking devices so the photographer doesn't have to hold the plunger down for several minutes.
the shutter protects the lenses, in film cameras, a smaller shutter behind the lenses open right as you shoot the picture, allowing light to hit the film for a fraction of a second. the film retains the light and color.
Like any other camera, the 'shutter' opens and closes to allow light to enter into the camera to be exposed on the film plane.
A pinhole camera is a very primitive camera that does not have a lens. To put it simply, a 'pinhole camera' is a light-proof box with a small hole punctured in one side. Light passes through this small hole and projects an inverted image on the opposite side of the box. The smaller the hole, the sharper the image, but the dimmer the projected image. A pinhole camera's shutter is usually manually operated because of the lengthy exposure times needed. It usually is made of a piece of light-proof material to cover and uncover the pinhole. Typical exposures range from 5 seconds to hours and sometimes days.
Shutter is the device on the camera that allows light onto the film or the digital camera's picture.
A camera shutter allows light to pass to the film or optical sensor for a specific length of time. The longer the shutter is open, the more light is allowed to pass. In lower light levels, the shutter will open for longer than in high lighting levels. Most handheld shots will use a shutter time of around 1/50th second or shorter. Exposure times longer than that may suffer blurred images because of camera shake.
The shutter speed is directly linked to the film or sensor sensitivity and the lens aperture. The wider the lens aperture (or lower F No) and the higher the sensitivity, the shorter the exposure time.
The shutter determines the length of time the film or sensor is exposed to light to create an image.
To open up and uncover the film for the needed amount of time.
controls the amount of light reaching the film/sensor-from nearly dark to the Sahara at midday, so the picture is viewable.
Most cameras don't have a dedicated shutter speed longer than thirty seconds. If you wish to take exposures longer than that, use the bulb function ('B' on most cameras). Bulb allows the shutter to stay open as long as the shutter button is held down. Get a locking cable release, switch camera to bulb, and you can take any length exposure you want.
The B setting stands for "bulb" and stems from days of yore when photographers sometimes used a small air tube connected to a squeeze bulb that they held in their hand. The camera end of the tubing was connected to the shutter. If they squeezed the bulb and held it, the air pressure activated the shutter which would stay open until they relaxed their grip on the bulb. By this means, they could open the shutter for longer periods of time than what the camera was capable of doing on its own. Modern cable releases are connected to the shutter button to perform the same function.
All cameras are equipped with a "Shutter Button", this button opens the shutter release light onto the image canvas, then automatically shuts the shutter. Then you have a picture.
Shutter speed is how fast your shutter opens and closes to take a picture on your camera. Shutter speed also has a lot to do with exposure. The higher the shutter speed (1/2000 example) the less light.
All cameras have multiple shutter speeds and depending the mode your camera is (Manual, Auto, etc...) the camera will choose what shutter speed it thinks will be appropriate for the picture. And most cameras will also not tell you the shutter speed you used, while some will.
there is no function of the aperture but there is a function of the shutter. the shutter opens and closes to a certain point, allowing light into the camera. The hole in the shutter is the aperture
That should be the shutter.
it is a device that is part another device mostly a camera that makes a shutter sound to tell you that the picture is taken

The plural form for the noun shutter is shutters.
