What is f-stop in photography?
When you’re in a dark room, your pupils will dilate to let as much light in as possible. Switch the light on and you’ll find that your eyes instantly contract so that you’re not blinded. On a camera, the aperture works in a very similar way. It expands to let in more light when it’s needed, and shrinks to keep it out, to ensure your photo isn’t over exposed. It does this by a measure known as F-Stops. The Aperture will have different levels to which is expands and contracts to, usually ranging from about F2.8 to F11 (keep in mind this can vary significantly depending on the price, range and lens of your camera). Despite how it may seem though, when your camera is on F2.8, the lens opening is wide, and F11 means that the opening is small. The higher the F-Stop, the smaller the aperture.
