For this assignment we had to work with aperture and learn how to get background blur with it. With aperture or the “F number” we know this is the size of the hole for your lens.The smaller the F number is the bigger the hole gets bigger this can possibly make the picture over exposed then the field of range gets shallower. That means that the bigger the F number the hole gets smaller but this can make it under exposed and your field of rage gets deeper.
