Aperture refers to the opening of a lens’s diaphragm through which light passes. Aperture is expressed as an f-number (written as “f/” followed by a number), such as f/1.4, f/2, f/2.8, /f4, f/5.6, f/8, f/11, f/16, f/22, or f/32. When changing aperture, you’re basically closing or opening the iris of your camera. Just like iris in your eye gets bigger in the dark and smaller when it’s bright. The lower the f/stop, the larger the opening in the lens, and thus the brighter the image, and vise versa. Hovewer, aperture also affects depth of field. We will discuss the depth of field more in another section. All you need to know for now is that the smaller the opening of the diagram is, the sharper your image will be. Next: ISO go back
