Aperture is hole that shutter creates to let in light to compose your image. The bigger the aperture, or smaller the f-stop (f/2), lets in more light. The shutter speed is how fast the shutter opens and closes. This has a major part to do with the lighting and whether the motion in your picture will freeze or blur. A high shutter speed (1/4000) will freeze all motion but majorily decrease light.

Each of these directly effect the overall exposure.

Aperture adjusts the size of the opening that lets light comes through. The bigger the opening, the more light that hits the film (or sensor).

Shutter Speed adjusts the amount of time that light is allowed to travel through the Aperture. A shutter that is open twice as long lets in twice the light.

(Thinking of it another way)

Let's imagine water instead of light.

To create a correct exposure, you need to fill a bucket with water. You want to fill the bucket to the top without overflowing.

Adjusting Aperture is like adjusting the size of a water hose. A bigger hose allows more water to travel through.

  • f2.8 hose = 8 gallons/minute
  • f4 hose = 4 gallons/minute
  • f5.6 hose = 2 gallons/minute

Adjusting Shutter Speed is like turning the hose on and off, leaving it open for an exact amount of time.

To fill a 4 gallon bucket you can:

  • use a f2.8 hose for 0.5 minutes
  • or use a f4 hose for 1 minute
  • or use a f5.6 hose for 2 minutes

If the bucket (your calculated exposure) is not filled to the top, then the image will be too dark. If the bucket is overflowing, then the image will be too bright.

The size of the opening and the amount of time it is open both directly effect the outcome.

The faster your shutter speed is, the more underexposed (darker) your subject/ scene will be. fast shutter speeds include 1/200th of a second, 1/320, 1/400, 1/500, 1/640, 1/800, 1/1000 and so on. If the shutter is slower (1/30, 1/40, 1/50 1/60, 1/100, 1/160) it will let more light in. with a slower shutter and moving objects, motion blur will occur, which is why a faster shutter is used to take action shots such as sports, and a slower shutter is used in Modeling Photography to capture those vivid colors and lights.

The shutter in the camera is responsible for letting light expose a sensor in a digital camera or film in a traditional camera. The size of the opening of the shutter and the time that it remains open to expose the media, determines the exposure of the image.

The shutter has two settings: F-stop (how large/small the opening and Shutter speed (how long it stays open).

These two settings are inversely related. As F-Stop increases, the speed decreases to get the same relevant exposure. and vice versa.

The shutter affects exposure by working with the aperature to control the light in an image. Shutter speeds vary for as long as you would like the "film" (CCD sensor) exposed to the light. The longer your shutter is open, the brighter the picture will come out - and your images will be more blurred if you move the camera. The faster the shutter is closed, your images will be darker, and less blurred when moving the camera. Hope his helps!

How exposure system works and affect the image?

Exposure is the combination of aperture and shutter speed. Aperture (measured in f-stops) determines the amount of light that will enter your camera. Shutter speed (measured in seconds) determines the amount of time that the shutter will stay open to allow light to enter.


What shutter speed will allow the least amount of light into the camera?

The highest shutter speed available to you will give you the darkest exposure, while the lowest shutter speed available will give you the brightest exposure


How does shutter work?

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.


Why is shutter speed used?

The shutter speed setting controls the picture exposure, or how dark or bright the picture will be. Wikipedia has some very good information on shutter speed and aperture.


On a manually-operated camera exposures can be made or manipulated with the shutter speed and the aperture one of these controls the output of the flash do you know which one?

The answer is Aperture. The Shutter Speed does not affect Flash output. You can prove this by setting up a camera with a flash in a room where you can control the lighting. Photograph an object in the room until you determine the best flash exposure...such as F 5.6, F 8, etc. Now that you know the F stop (aperture) that allows the proper amount of flash, turn off the room lights so that there is virtually no ambient light in the room. Leaving your camera set to the correct aperture (F stop), take different exposures by changing the shutter speed each time while not changing the aperture. You will see for yourself that the flash exposure is the same with each exposure even if you try one shutter speed at 1/60 and another at 1/2 second. The shutter speeds would only make a difference in the overall exposure if there was existing ambient light...then the exposure would become light or darker depending on the shutter speed. With a slower shutter speed the scene would be brighter as more ambient light was taken in, but the shutter speed did not affect the flash, only the ambient light.


What two variables on a camera control the exposure of the film?

shutter speed and lens aperture


What are 3 things that controls exposure?

Shutter speed, aperture, and ISO are the three main factors that control exposure in photography. Shutter speed determines how long the sensor is exposed to light, aperture controls the amount of light entering the camera, and ISO adjusts the camera's sensitivity to light.


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.


Does shutter speed affect the quality ofa picture?

yes, it can. it depends on the lighting. you can use a larger shutter to capture colors, for example a sunset.


What type of shutter do you use in the evenings?

I assume that you are looking for the shutter speed to take shots in the evening - this will depend on the aperture you are using and the ISO setting. Your need to combine all three to get the correct exposure. www.goldprints.com


What happens when you open up the lens aperture but do not change the shutter speed?

You will increase the film exposure compared to what the on board light meter is suggesting. This is known as over exposure, but that is a relative term. "Over exposure" is not necessarily a bad thing.


How do you take pictures in a semi to dark room?

use a flash or try time exposure by slowing the shutter speed down.
