Objective: Students will understand how shutter speed affects motion and will use TV Autoexposure mode to manipulate how motion is captured in a series of images.
Capturing Motion
Photographers have two options when capturing motion. They may purposely "blur" the motion to emphasize the movement or speed of the subject, or they may try to "freeze" their subject in that exact specific motion. In order to achieve both desired effects, photographers need to manipulate the shutter speed.

How Shutter Speed Affects Motion:
The Faster your shutter speed, the sharper (more clear) your image will be. The slower your shutter speed, the more motion blur your image will have.

Set Your Camera to Time Value Mode (TV)
Time Value Mode lets you control the shutter speed using the dial next to your shutter button. While in TV mode, your camera will automatically select your aperture (f-stop) for you, to try to balance out your exposure. You may still need to set your ISO.
ISO should be set higher if you are shooting inside or using a fast shutter speed (try 800 or auto).
ISO should be set lower if you are shooting outside or with a slower shutter speed (100 - 200).

Assignment:
Today you will capture a moving subject with a fast shutter speed and again with a slow shutter speed to compare how motion is affected. Go outside and have a model jump, flip, dance, or do anything that includes motion! Other possible subjects could be a pinwheel blowing in the wind, a ball being thrown in the air, leaves being thrown in the air, etc. Be creative! With the slow shutter shoot, any time that you are using a shutter speed of 1/30th of second or slower, a TRIPOD IS REQUIRED. This is because during that long of an exposure, camera shake will occur from hand-holding your camera. This will produce an image that is blurry all over, not just the moving subject.
