WebExposure value is a base-2 logarithmic scale defined by (Ray 2000, 318): = , where N is the f-number; t is the exposure time ("shutter speed") in seconds; EV 0 corresponds to an exposure time of 1 s and an aperture of f/1.0. If the EV is known, it can be used to select combinations of exposure time and f-number, as shown in Table 1.. Each increment of 1 … WebThe (natural) exponential function f(x) = ex is the unique function f that equals its own derivative and satisfies the equation f(0) = 1; hence one can also define e as f(1). The natural logarithm, or logarithm to base e, is the inverse …

WebF number is a correlation number used in the analysis of polycyclic aromatic hydrocarbons as a descriptor of their hydrophobicity and molecular size.[1] It was proposed by Robert … The f-number accurately describes the light-gathering ability of a lens only for objects an infinite distance away. This limitation is typically ignored in photography, where f-number is often used regardless of the distance to the object. In optical design, an alternative is often needed for systems where the object is not far … See more 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").
