Quick Guide: Aperture and Depth of Field (With Examples)

My trusty Nikon D3000 has been with me for many years, originally bought for my A-Level Photography classes. After my A-Levels, my Nikon became forgotten about, collecting dust for years until I picked it back up again in March 2016. Welcome back Nikon <3

I’ve recently started to learn how to get the most out of my camera again. Starting with how to use aperture and create a variety of depth of field photographs.

Here’s a quick explanation on both depth of field and aperture, using my own photos;

Depth of Field

Knowing how to control the depth of field can hugely change the result of your photographs.

To control the depth of field, you simple need to learn the basics on how to control the aperture then after you know the basics, it’s practice makes perfect.

The lower the f/ number, the more of the photograph will appear blurred and the higher the f/ number, will allow the whole photo be in focus.

For example;

In this photograph,you can see the lower aperture photo on the left (f/3.5) had a blurred foreground and background, which allows focus on the middle section.

On the right, the higher aperture (f/22), allows the entire photograph to be in focus.

It is recommended to use a tripod whilst controlling aperture. The higher the f/ number, the more stable the camera will need to be.

Aperture

Aperture is the diameter of the hole which allows light to enter through the camera. Controlling the amount of light entering through the lens allows you to control the depth of field. You can control the light by switching your camera to the ‘A’ (Aperture) setting

Large Aperture = Small f number = Shallow depth of field

Small Aperture = Large f number = Deeper depth of field

f/3.5

f3-5

f/5.3
f5-3

f/8

f8

When I first started learning about the aperture, it seemed that the aperture numbers and meanings were the wrong way round. Especially as f/3.5 had a larger aperture than f/22, but once you’ve learnt the basics and put the aperture to test yourself, you will soon get the hang of it.
