• In optics, the f-number of an optical system such as a camera lens is the ratio of the system's focal length to the diameter of the entrance pupil ("clear aperture").
• In photography, exposure is the amount of light per unit area (the image plane's illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens F-number, and scene luminance.
• Depth of field changes linearly with F-number and circle of confusion, but changes in proportion to the square of the focal length and the distance to the subject.
• Reducing the aperture size (increasing the f-number) provides less light to sensor and also increases the depth of field, which describes the extent to which subject matter lying closer than or farther from the actual plane of focus appears to be in focus.
