How to Use the Shutter to Control Motion in Photography

Shutter speed can reduce the blur that is the result of objects moving across the camera's view. The longer that the shutter is open, the less sharp an object will be in motion across the field of view. Speeding up the shutter, or reducing how long light is allowed to enter the camera, gives varying amounts of control over the effects of motion and of blur. It is possible, with a fast enough shutter speed, to freeze motion. The following steps will help you perfect your shutter technique.

Instructions

1. 

   Practice photographing objects in various speeds of motion. Using the slowest shutter speed that your camera allows, see what effect a longer duration has on objects moving at varying speeds across the camera's view.

2. 

   Increase shutter speed incrementally for an object moving at the same speed across your view. You will see the object with increasing clarity as the shutter speed increases.

3. 

   Use blur to create an impression of motion. Use slower shutter speeds on objects that are slowly moving. This increases the sense of movement and speed. Blur should be used when it fits with the overall composition and commentary of the intended picture.

4. 

   Freeze motion to create commentary about objects that are moving quickly across your view. You can create contrasting images with rapid shutter speeds against secondary subjects. Play with reality for symbolic effect. Never freeze just for its own sake.

Tips & Warnings

• Keep in mind that motion and shutter speed only refer to objects moving across the camera's view, not toward or away from the camera.

• Understand that slower shutter speeds require using a tripod for control of the camera.
