Aperture priority lets you set the aperture you want and the camera sets the shutter speed for you. You use it when you want to control depth of field. Shutter priority lets you set the shutter speed you want and the camera sets the aperture for you. You use it when you want to control how motion is rendered in the photograph. Program mode sets both shutter speed and aperture for you. Use it when you are not concerned with aperture or shutter speed control.

The Shutter and the Aperture are the two controls the Shutter is used to control how long the Film is exposed for and Aperture is used to control how much light is let in
shutter speed and lens aperture
The shutter of a camera opens and closes allowing light into the camera, the hole in the shutter is the aperture.
there is no function of the aperture but there is a function of the shutter. the shutter opens and closes to a certain point, allowing light into the camera. The hole in the shutter is the aperture
Aperture Priority has the camera set the shutter speed for you allowing you to set the aperture and it will set what shutter speed it thinks is best for your current light situation.
Aperture and shutter speed control the amount of light that passes from the lens to the film or digital sensor of a camera. Aperture is the size of the opening within the lens. The lower the f-stop number (1.4 for example) the larger the opening and the more light is passed through. Shutter speed is closely related. It is the amount of time that the lens is open. The combination of the size of the opening in the lens and the amount of time that the lens is open determine the exposure.
Shutter speed, aperture, and ISO are the three main factors that control exposure in photography. Shutter speed determines how long the sensor is exposed to light, aperture controls the amount of light entering the camera, and ISO adjusts the camera's sensitivity to light.
The amount of time that the shutter remains open - allowing light to pass through it to form the image. Generally - a lower shutter speed would be combined with a smaller aperture and a higher shutter speed with a larger aperture to correctly expose the image.
Exposure, in digital or film photography, is determined by aperture and shutter speed. On a manual camera, the user selects both values.On an automatic camera, there are four possibilities:Manual mode. User selects both aperture and shutter speed.Shutter priority. User picks the shutter speed and the camera adjusts the aperture to ensure proper exposure.Aperture priority. User picks the aperture and the camera adjusts the shutter speed to ensure proper exposure.Program mode. The camera selects both values.
