Understanding Aperture

Aperture is the size of the opening in the lens when a picture is taken. When the aperture is low is allows more light to enter and has a select focus. It makes the subject appear clear and in focus and the background is blurry. When there is a high aperture less light enters and there is a large depth of field. The whole picture appears to be in focus and is clear. A low aperture usually has a faster shutter speed and a high aperture has a slower shutter speed in order to remain balanced.
