What is aperture? Aperture is the opening gap in the lens which allows different amounts of lighting into the photograph being taken. As you move between bright and dark environments, the iris in your eyes either expands or shrinks, controlling the size of your pupil. However in photography terms the “pupil” of your lens is called aperture. You can shrink or enlarge the size of the aperture to allow more or less light to reach your camera sensor. Aperture can be seen on the camera by looking at the f/stops and is generally written as numbers such as 1.4, 2, 2.8, 4, 5.6, 8, 11 and 16.
What is Depth of field? Depth of field is an important aspect in the taking of photographs. Depth of field is the distance between the closest and farthest objects in a photo that appears acceptably sharp. Now your camera can only focus sharply at one point. But the transition from sharp to unsharp is gradual. Depth of fields in photographs can be seen in foreground, middle ground and background.
