Shutter Speed•

•If you want to capture still photos of fast motion (like pressing pause on your DVD) you have to use a fast shutter speed.

•Many sports use very fast shutter speeds to capture the peak moment and freeze it in time.

•If the subject of your photo is not moving, or you want to show the passage of time (with a running river or waterfall), then you can use a slower shutter speed.

How does shutter speed effect your image?

It freezes action or shows the passage of time

Shutter Priority

•Many digital cameras can be set to shutter priority mode. •In this mode, you set the shutter speed and the camera automatically selects the aperture so that the photograph has the right exposure.

Shutter Speed and The Real World

Situation Setting Speed

A hummingbird is hovering above a flower, and you don't want it's wings to be blurry

Very fast shutter speed 2000 to 4000

Kids are playing soccer, and you want the images to be sharp and clear

Fast shutter speed500 to 1000

You are taking a portrait of your favorite pet, and your pet is being polite and sitting still

Moderate shutter speed 125 to 500

A carousel is spinning and you want to show how fast it is going by letting the horses blur

Slow shutter speed and tripod 8 to 60

You want to take a photograph of your favorite building at night Very slow shutter speed and tripod 8" to 30”

Situation:

The seagulls were just about to take off, and were opening their wings.

In order to freeze the motion of the wings, Photographer had to use a fast shutter speed of 1/750 of a second.

Very Fast Shutter Speed

1/750

Situation:

Calm day and the grass was not moving at all. Photographer did not need to capture fast motion, and did not want the photo to look blurry.

The shutter speed for this photo is 1/180 of a second

Moderately Fast Shutter Speed

1/180

Situation:

Photographer wanted to capture this waterfall in motion, and create a blurry look for the moving water.

The shutter speed was set to 1/6 of a second.

This shot required a tripod, otherwise the greenery around the waterfall would also look blurry

Slow Shutter Speed

1/6

Situation: Night time, semi-busy street

8 second exposure on a street at night. This photo could not have been taken without a tripod.

The red and white streaks in the photo are the lights of passing cars. Since the shutter was open a long time, the cars passed by completely while the photo was being taken.

Very Slow Shutter Speed

8 sec.

COnfused???Shutter speed is, apart from aperture,

It is control by the shutter speed dial. Shutter speed means timing and duration of opening and closing of the shutter curtain at the back of the camera. A fast shutter speed will freezes action while slower speed creates blurring effect. A shutter speed of 1/125 will allow one time more the amount of light to reach the film than 1/250, the amount of light is double on the next scale of 1/60 to 1/125 etc.

Slow Shutter speed

Realize that 1/2000 of a second is incredibly fast and is not a shutter speed that you will typically use. The most common shutter speeds are anywhere from 1/500 to 1/60. If you want sharp photographs while holding the camera in your hands, you cannot use shutter speeds much slower than 1/60 because it's hard to hold the camera steady. Slow shutter speeds blur motion, and you are creating motion by holding the camera in your hands. You can solve this camera shake problem by stabilizing the camera on a tripod.Some of the new digital camera models offer an anti-shake feature. These features produce crisp photos even when you are hand-holding the camera with a shutter speed less than 1/60.
