The power of a large aperture.

Get beautiful photography effects with a large lens aperture.

An aperture is the adjustable lens opening that controls how much light gets into your camera. The larger your lens aperture, the more light it will let in. It’s expressed in what’s called an f-stop number, which is determined by the ratio of your aperture diameter to your lens focal length. Your lens’ highest aperture, usually f/1.4, lets in the most light, while your minimum aperture, around f/16, lets in the least light.

When it comes to your lighting, composition, and desired effect, aperture can make all the difference.
