f-stop

Aperture shapes a photograph more decisively than any other setting. It governs how much light reaches the sensor, and it decides whether the background behind your subject dissolves into a soft wash of colour or stays sharp enough to count the leaves.

Different scenes call for different apertures. The settings that suit a portrait taken on a stoep in the last hour of afternoon light are nothing like the ones you would reach for at the top of Chapman’s Peak Drive with the whole Atlantic seaboard in front of you. This guide works through what aperture in photography actually is, how it interacts with shutter speed and ISO, and which f-stops to reach for across portraits, landscapes, night scenes, astrophotography and sport.

What Is Aperture in Photography?

The aperture is an adjustable opening inside the lens, formed by a ring of overlapping blades. Widening or narrowing that opening controls how much light passes through to the sensor. The measurement describing how far open it sits is

Whether you are photographing wildlife in Kruger National Park, shooting rugby action in Pretoria, or capturing sunsets along the Cape Town coastline, understanding depth of field can dramatically improve your photography. Depth of field controls how much of your image appears sharp, helping photographers create everything from creamy portrait backgrounds to crystal-clear landscape scenes.

In this guide, we explain what depth of field is, how depth of field works, and how South African photographers can use it creatively for portraits, sports, wildlife, and travel photography.

A shallow depth of field keeps only a small part of the scene sharp, while a deep depth of field keeps much more of the image clear.
