Shutter Speeds

Firstly exposure means how much light hits the sensor in a camera. the ways in which to control this is aperture and shutter speed.

Shutter speed measures how long light is allowed into the camera. Shutter speed is measured in fractions.

A fast shutter speed e.g 1/1000 will freeze the movement in an image so the image appears sharp.

A slow shutter speed e.g. 1/4 sec, blurs movement in an image so the moving objects in the image appear less sharp.

Light painting is where a camera records light/movement in an image for as long as the shutter is open.
