Aperture is probably the most difficult pillar to learn among three – ISO, shutter speed, and aperture – in digital photography. I previously discussed the ISO and shutter speed. Now I am going to discuss the aperture in simple language.

What is Aperture in Photography?

In short, the opening in a lens through which light passes to enter the camera body is known as aperture.

Aperture is basically the hole in the camera lens from where light enters into the camera body. The camera aperture can be changed to control the amount of light the camera sensor gets.

How Aperture Affects Exposure?

Photography in a digital camera can be severely affected by aperture. Brightness or exposure will be affected if you change the aperture. The larger the aperture will be, the more light your image will get.

On the other hand, small aperture will send less light into the camera body and the images will be darker.

During the night time or in dark places, aperture should be selected at a large scale as this would capture as much light as possible for the image. Besides, to decrease the light in your image, aperture should be set at a small scale.

How Aperture Affects Depth of Field?

Depth of field is another crucial side where aperture can affect. Depth of field is actually the amount of photograph that appears sharp from front to back. Not all the images have sharp front and back. Some of the images have either sharp front or sharp back.

A large aperture offers more brightness and small aperture offers less brightness to your images. Besides, a large aperture will leave a large amount of background blur and small aperture will do the opposite.

Many photographers find aperture confusing in the beginning. If you are a newbie in digital photography and aperture is confusing you then there is nothing to be worried about.

With a bit of practice and time, the issue will go away and you too will be an expert of aperture.
