Aperture Aperture being one of the three main elements in photography while other two being shutter speed and ISO, it can be used to control the overall exposure. Aperture determines the amount of light entering to the camera by varying the diameter of the iris. For example if the iris is wider, more light can go through to the camera and if the iris is narrower, relatively small amount of light can go through.    Figure 1.0 lens with high and low aperture The F-Stop value (Measurement of Aperture) Stop value in photography act as a measurement of exposure and will depend on the 3 major elements aperture, shutter speed and ISO. When it comes to aperture, it is denoted as f-stop. With the f-stop value you can determine the depth of the field. In lower f-stops, amount of light can pass through from the lens is high and pictures appear to be blurry this is called a shallow depth of field and this lowers the clarity of the entire picture. A high f-stop picture is les
