Let’s look at the differences between using a wide and narrow aperture and what each one of them entails.Ī simple infographic that displays aperture range for easy understanding. Understanding when you will benefit from using a wide or narrow aperture will help you achieve a result that is in line with your creative vision. Most modern cameras will allow you to adjust the aperture by changing settings on the camera body, however, some lenses also have a physical aperture ring around their barrel. For example, some lenses are able to open up to f/1.2 while others might only open up to f/4. Each lens differs in terms of the aperture it has available. This number helps you to understand what kind of aperture you have set on your camera or lens. This will appear on your camera as, for example, f/2 or f2, depending on which camera brand you use.

If we look at a bright scene, the iris in our eyes shrinks, however, if we enter a dark environment, it expands to let in as much light as possible. It functions in the same way our eyes do. The larger the opening, the more light that will get in. Similarly, the smaller the opening, the less light that will be let in. The aperture that you set impacts the size of that hole.

Light then hits the sensor before the shutter mechanism closes again. When you press your shutter to take a photo, the shutter mechanism opens to let the light in. In photography, this term relates to the opening of a lens. The literal meaning of aperture in optics is ‘a hole through which light travels’.

Here, a tripod or an effective image stabilization system can help. These apertures are also harder to use when hand-holding a camera, as the smaller the aperture the longer the shutter speed you need – and at some point you simply won't be able to hold it steady enough to produce a sharp image. Small apertures, meanwhile, can make an effect known as diffraction more prominent, which also has a softening effect on images. Particularly wide apertures can also be tricky to use in bright conditions, as your camera may not be able to use a fast enough shutter speed to keep everything exposed correctly, which leads to overexposed images. Wide apertures are great for isolating subjects from their backgrounds, but images can be softer at these settings due to an effect known as spherical aberration. There are issues with using both very small and very wide apertures, so you need to judge this from scene to scene to understand which setting is most appropriate.

Depth of field concerns the extent to which different areas in the scene are rendered in focus, and a photographer will typically use a medium or small aperture to achieve more definition throughout. Whichever mode you use, changing aperture has an effect on depth of field. Opening up, meanwhile, means doing the opposite. Ever hear these terms? Stopping down the lens or aperture simply means to make the aperture smaller, such as from f/8 to f/11.
