Aperture is measured in f-stop numbers (i.e f/2 or f/22 as you can see in the below diagram). The smaller the lens opening, the higher the f-stop and the higher the f-stop the less light, therefore more of the image will be in focus and vice versa. When we alter the aperture we also must consider whether we…
