What is Aperture?
Aperture is a hole in which light travels through deterring the brightness of a photograph from a camera. When you press the shutter release button of your camera a hole opens up that allows your cameras image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in and the smaller the hole the less light. Aperture is measured in ‘f-stops’. The lower the F-Stop (e.g. f/2.8) the wider the opening of the aperture and the higher the aperture (e.g. f/22) the smaller the opening of the aperture. |

What is shutter speed?
Shutter speed, also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely. f the shutter speed is slow, it can create an effect called “motion blur”, where moving objects appear blurred along the direction of the motion. |

What is Exposure?
A photograph's exposure determines how light or dark an image will appear when it's been captured by your camera. Believe it or not, this is determined by just three camera settings: aperture, ISO and shutter speed (the "exposure triangle"). Mastering their use is an essential part of developing an intuition for photography.
The example on the left shows on the very far left the photograph being under-exposed, in the middle is a perfect exposed photograph and the last is over exposed. |
