Aperture and Shutter Speed
In a Single Lens Reflex camera (SLR), the aperture and shutter speed settings regulate the amount of light that will expose the film. The aperture is the opening that lets light into the camera and the shutter speed is the amount of time of the exposure. The photographer can set each control to get the correct exposure and create a specific effect in the photograph.
Aperture and Depth of Field
The size of the aperture opening affects the depth of field, or what and how much of the image will be in focus. The larger the aperture opening, the smaller the depth of field. Pin hole cameras have a long DoF because the aperture opening is very small.

Shutter Speed and "Capturing" Motion
The amount of time the shutter curtain is open for will affect if a moving object will be clear or blurry, thus "capturing" or freezing the moving object with a fast shutter speed. If motion blur is desired, a longer or slower shutter speed will acheive this effect.
