Aperture refers to the opening of a lens's diaphragm through which light passes. It is calibrated in f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16. The lower f/stops give more exposure because they represent the larger apertures, while the higher f/stops give less exposure because they represent smaller apertures. This may seem a little contradictory at first but will become clearer as you take pictures at varying f/stops. Be sure to check your manual first to learn how to set your camera for Aperture Priority, then try experimenting to get comfortable with changing the aperture and recognizing the effects different apertures will have on the end-result image.

Bad Example:
This is a bad example of aperture as in the picture there isn't the right amount of light around the subject of the photo (leaves/branches), as I didn't let enough light in the lens.
It is very boring as no colours stand out against the background. Also there isn't an obvious area of interest, so the image doesn't grab your interest.

Good Example:
This is a good example of aperture as I let a good amount of light into the lens, so the image is bright and visible. It also looks good as the image is very crisp and clear. Your attention is brought straight to the tree trunks and branches as the brown stands out against the green leaves and blue sky.
