What is the depth of focus of a camera?


depth of focus is the range of distances that will be in focus in a picture taken by the camera with specific settings. Depending on the settings of the camera, the depth of focus can be very small, ranging in millimeters or centimeters to very large - hundreds of meters. The most important setting that will determine the depth of focus is the aperture used in the lens when the picture is taken. The aperture is how widely open the lens is and how much light is allowed to pass through it. A low f-stop or big aperture will minimize the depth of field, while a high f-stop or small aperture will maximize it. Depth of field is an element that photographers use in composition to blur or sharpen elements of the photograph, thus emphasizing or de-emphasizing certain aspects.
