A is for Aperture – #AtoZChallenge – 2020

A is for Aperture

The aperture is the opening in a camera through which light passes to get to the film. It is adjustable much as our own pupil expands or contracts with changing light conditions.

In photography, the size of the aperture not only affects the amount of light that gets into the camera (and onto the film) but also characteristics of the focus of the object being photographed.

A smaller aperture allows less light in. However, the resultant image is more likely to be in sharp focus. Larger apertures result in reduced focus, as anyone who’s had their eyes dilated will tell you!
