How does the shutter affect exposure?

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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!
