So when you adjust your aperture, you will likely also need to adjust your shutter speed.įor example, a low F-stop number means a wider aperture and more light. In different ways, both control how much light enters the lens. Shutter Speed and ApertureĪperture and shutter speed work together. The lower your F-stop number, the wider the aperture, and the more light that is allowed through the lens. The F-stop is a unit of measurement for the aperture. Too much light and your photograph will be over-exposed. Aperture controls the intensity of the light as it hits your camera’s sensor. Your camera lens is like the eye of your camera. In bright light, the pupil contracts to decrease the amount of light that gets in. Aperture and F-stopsĪs light dims, the human eye will attempt to bring in more light so we can see better.
