What Is Aperture In Photography? (revisited)

Aperture in photography is the size of the opening in the camera lens which light passes through to get to the camera sensor. The aperture can be made larger to let more light in, or smaller to let less light in. The aperture is used in conjunction with the camera shutter speed to get the correct exposure. The aperture is also used in conjunction with shutter speed and ISO to take photos with different camera settings. The aperture used also determines the depth of field in an image, which is the amount that is sharp from front to back.
