Bronx Community College | Digital Photography | Prof. Jacques Name _______________________________________ Controlling Light | Shutter Speed + Aperture | Study Guide To make a correct exposure, so that your picture is neither too light nor to dark, you need to control the amount of light that reaches the digital image sensor. Shutter Speed = Exposure Time The shutter speed (the amount of time the shutter remains open) is one of two controls your camera has over the amount of light entering the camera. Aperture = f-Stop The aperture size is the other light control (how big or small is the hole that allows light in the camera). By controlling the amount of light that enters the camera, the shutter speed also affects the way that moving objects are shown.
