Motion Module 4

Shutter speed controls the amount of time that light is allowed to enter the

camera. The speed of the shutter will affect how motion (subject movement) is

recorded.

Shutter Speed controls Motion

Shutter Speed Video

Shutter Speed is measured in fractions

of a second.

A faster the shutter (1/500) = more “frozen” movement

A slower the shutter (1/2) = more blurry movement

Three ways to capture motion in photos:

Stop Motion

Blurred Motion

Panning

Stop Motion

Your goal is to “freeze” the motion.Both subject and background should be in

focus.

Stop motion is achieved using a fast shutter speed.

Blurred Motion

Your goal is to blur some movement, while not losing the vital information that the subject

offers.

Your subject should be blurred, the background in focus.

Blurred motion uses a slower shutter speed.

Panning

Panning moves the camera along the subject’s path.

Your subject will be in focus (relatively) and

your background will be blurred in striations.

Panning uses a slower shutter speed.

What if it’s all blurred?

Using a Tripod…

When using a slow shutter speed, your camera will record hand shakes. Use a tripod or other

props to keep your camera still.

Why don’t you need a tripod with a fast shutter speed?

What kind of motion is this?

Module 4 Assignments:

1. Take one “Stop Motion” photograph using a fast shutter speed or Action Mode (Running Man, Children, Pets).

2. Take a “Blurred Motion” photograph using a slow shutter speed or with Auto Mode. Only what is moving should be blurry—set your camera on a tripod or stable surface.

3. Use the “panning” technique to capture motion in a photo. Your subject will be focused and background blurred in the direction of your moving camera. Try different camera settings and subject.

4. Take a fourth image that involves Auto Mode, and then change the shooting options (FAST Shutter Speed or Running Man/Children/Pets) and take the same photo again. Upload both pictures as “Comparison” photos.
