- The aperture, also called the iris, is the opening in the lens that lets light in. You can adjust the aperture by either adjusting a ring on the lens or with your camera, if your camera has the ability to control your lens. We'll look much more at lenses later in this series, but for now it's just important to understand how exposure is affected when we adjust the aperture. Of all three points in the exposure triangle I find myself using aperture to control exposure the most often. As we close the aperture, we let less light in, reducing our exposure. Opening the aperture increases exposure. However like all three components of the exposure triangle there is a side effect. As we close the aperture down we increase the depth of field. Now the depth of field is the area that is in focus. My iPhone and my GoPro both have a huge depth of field so I can just whip them out on the go and capture whatever is going on knowing that most of the image will probably be in focus, but if we open…
