Expert Answer:

If you are photographing fast moving objects such as cars or people running you need to select fast shutter speeds to capture the sharpest picture you can.

As well as letting more or less light into the camera the size of the aperture you choose governs the 'Depth of Field'. Depth of field means the amount of the picture, from foreground to background, that is in sharp focus. A smaller aperture will give you a greater depth of field and a larger aperture will give you a more restricted depth of field. This characteristic can be used to good effect in many ways.While photographing large landscapes we keep large aperture and while photographing small objects we select short aperture.
