This is because wider apertures will make it easier to shoot in lower light scenarios. If the portrait photographer works primarily with natural light, then they will favour a ‘fast’ lens with wide open apertures such as f/1.4. Portrait photographers work in different styles, with some using only natural light and others adding an artificial light. Being able to create a blurry background is beneficial when you want to isolate your subject, whether it is a person, a coffee cup or perhaps a single flower in a vase. In what scenarios would we benefit from choosing a wide aperture? People, food, and product photographers will appreciate being able to use a lens that can open up wide. Wide aperture creates a blurry background. What this translates to in photographs is blurry backgrounds. When you are using a wide aperture, such as f/2, you are creating a shallow depth of field, meaning, a shallow plane of your image is in focus. This gives you more room to be creative because it determines the area that appears sharp in your photos. The aperture allows you to control the depth of field in your images.
It might appear confusing and it still causes bewilderment amongst photographers at times, that using wide (or large) aperture actually means using a small number, such as f/2.

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’.
