To get the exposure level on the sensor correct - it's important in Photography on film also. Many cameras attempt to do it automatically.

Do digital cameras have shutters?
Short answer: Yes, if you define "shutter" widely enough.Long answer: Rather than a physical shutter as one would have with a film camera, many digital cameras simply turn the sensor on and off as needed (called electronic shutter). This is usually used in point-and-shoot digital cameras. A digital SLR camera, on the other hand, will usually have a physical shutter which opens for the needed duration, just like a film camera. Some SLR cameras, like the Nikon D40 (and probably many others) use both a physical shutter and an electronic shutter; having the latter permits almost unlimited flash sync speed.
What is aperture priority of digital camera?
Exposure, in digital or film photography, is determined by aperture and shutter speed. On a manual camera, the user selects both values.On an automatic camera, there are four possibilities:Manual mode. User selects both aperture and shutter speed.Shutter priority. User picks the shutter speed and the camera adjusts the aperture to ensure proper exposure.Aperture priority. User picks the aperture and the camera adjusts the shutter speed to ensure proper exposure.Program mode. The camera selects both values.
How does shutter speed control the amount of light entering a camera?
The Shutter Speed. If the shutter speed is positioned at 2000 you'll have a very quick exposure, this is best used if its very bright outside. If the shutter speed is at 75, you'll have a very long exposure, best used if its cloudy or dark.
How can you find the number of shutter clicks taken on a digital camera?
Some cameras keep a running total in the picture numbering system. See your manual.
What causes shutter lag?
In a mechanical shutter it is the time that it takes for the mechanical components to mesh and begin the movement of the shutter blades. These components must also build up the forces necessary to move against the springs that hold the blades in the closed position. This build up of forces takes some finite amount of time to overcome, hence a lag time. Then, depending on mass of the shutter blades there is a finite time it takes for the blades to move to the open position. This is due to inertia. (Inertia is the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force.) In an electro-mechanical shutter additional lag times are provided by the inductance of the actuating mechanisms, (usually some electro-magnetic actuator). In these cases the time it takes for the actuator to build up the energy necessary to be able to overcome the "at rest" forces causes additional lag. Shutter lag is a property that shutter manufacturers work very hard to reduce to a minimum required duration. ****************** While technically correct, shutter lag in a modern non-digital SLR is virtually undetectable. The questioner was probably referring to the lag time of a non-SLR digital camera, which as most people have observed, can be a pain in the butt. The answer in that respect is that the lag is due to the time it takes the image to be converted to digital information. High priced digital SLRs have much less lag as their processing time is much shorter. The trade-off is the dent it puts in your wallet. Micron.
Is there a measurement for shutter lag on digital cameras?
There is no measurement for shutter lag, unfortunately, on digital cameras.
What shutter speed do you need to take a picture of a lighting strike with a digital camera?
real fast . wide open shutter
What is the best quality camera with the slowest shutter?
I am not sure if you are asking about a digital camera or a old style camera. If you want a good older camera that would be a Cannon as you can set the shutter speed on it. If you are talking about a digital camera then you should hold the shutter button down longer.
What does the smile shutter mode do in the Sony Cyber-shot DSC-H20/B Digital camera?
The Sony Cyber-shot DSC-H20/B Digital cameras smile shutter mode automatically captures an image when your subject smiles without having to press the shutter.
What digital camera models have a remote shutter release?
You can buy shutter releases for basicly any camera, for under $10. Have a look on ebay.com
How can use The Shutter Angle in Video?
Shutter Angle refers to the length of time film is exposed in a motion picture camera, based on the shape of the rotary shutter. 180 degrees is considered normal (when shooting at 24 frames per second). This means the film is exposed for 180 degrees or half of the rotation of the shutter or 1/48th of a second. The primary purpose of changing your shutter speed is controlling how much motion blur is captured. The slower the shutter (the larger the shutter angle), the more motion blur. In some video cameras you can crank your shutter speed higher to create a stop-motion effect or slow your shutter to 1/30th or 1/24th and create a blurring effect for specific shots. I have also heard of people using a slower shutter because it looks more "filmic" this is a matter of taste. All video cameras (to my knowledge) that allow for manual control of the shutter speed give these controls in 1/Nths of a second (1/48th, 1/60th). If you are shooting with a conventional video camera in the United States or another NTSC country your typical shutter will be 1/60th, meaning each frame was captured over 1/60th of a second. For Europe and Asia, along with most of Africa, South America, Australia your shutter will be 1/50th. Some newer digital video cameras targeted towards digital cinema allow you to display your shutter speed in degrees, as if you were controlling shutter angle (Panasonic AG-HVX200 as an example). Also they allow you shoot at 24 frames per second and to use shutter speeds that fit closer with that frame-rate, like 1/24th, 1/48th.

What is shuterspeed on a camera?
the shutter speed is how fast the shutter can go eg. an dslr has a faster shutter speed than a digital camera the shutter is a part on the camera that opens and closes when it opens it draws the light from the object focused on and places it on the lcd screen of film giving you your pic
What are disadvantages of using a digital camera?
Shutter lag is the most commonly cited problem with digital cameras, because of the time it takes for auto focusing and the activation of the picture capture mechanism, often in situations where timing is important like sports events, the time between pressing the shutter button and the actual time the camera records the image can mean the difference between getting or losing the shot.
Why does the shutter on a digital camera depend on resistance change?
That doesn't come standard, probably a factory defect.
What initials are used to designate using shutter priority on a digital camera?
On many cameras it is "TV" for Time Value.
How do the shutter and lens of the camera work together to form an image?
In 35mm or digital camera there is a type of shutter or lens that controls how the outcome of the image is. These two things are very important in how the images exposure, depth of field, clarity or lack of, etc. effect the photograph. Behind the lens and shutter in a camera is the film or in digital, sensor chip. The film or sensor chip reads the light that passes through the lens. The shutter controls how much light is being passed through and the lens is what allows you to get the image that you're looking at in the same perspective and location as you want. The shutter speed can make images look like they're frozen, a slow shutter speed can make something look like they have movement. The Lens is the medium that replicates what you're looking through in the eye hole that makes the same image on the film or sensor chip.
