Shutter Priority is represented by TV (Time Value) on Canon cameras and S (Shutter Priority) on many other cameras. Either way, Shutter Priority is useful when you want to control the Movement (action or blur) in your scene.

For capturing the action and freezing a moment in time, choose a fast shutter speed like 1/250 of a second or higher. The camera will make the rest of the exposure decisions for you.

If you’d like to blur the movement in your scene for a sense of motion, use a slow shutter speed like 1/20 of a second or lower. The camera makes the rest of the decisions for a proper exposure. *Note – if you use a shutter speed of 1/60 sec or slower you’ll need to stabilize your camera on a solid surface or with a tripod.

Check your camera manual to find out which dial or button you need to press to cycle through the aperture and shutter speed choices on your camera.
