Not all lenses are designed the same and some allow a lot more light to pass through them than others. We’ll get into the reason for this as we progress through the article.īryce Canyon landscape f/13 Maximum Aperture Most of the time, people do not care what the minimum aperture of a lens is, but they almost always care what the maximum aperture is. Different lenses have different maximum and minimum f-stops. For example, an f-stop of f/32 would be considered a very small aperture, whereas an f-stop of f/1.4 would be considered a very large aperture (see diagram below). The larger the f-number, the smaller the aperture is. Aperture Size – F-StopĪperture settings are referred to as f-numbers and individual settings are f-stops (eg. Not only does the aperture affect the brightness of our photos, but it also controls how blurry our background is. Varying the size of this aperture has a dramatic effect on the look of your photo and along with shutter speed and ISO, it’s also part of our exposure triangle.
