In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph. [1] The amount of light that reaches the film or image sensor is proportional to the exposure time.
t is the exposure time ("shutter speed") in seconds [2] The second line is just applying the quotient identity of logarithms to the first line. 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.
Exposure is a combination of the length of time and the illuminance at the photosensitive material. Exposure time is controlled in a camera by shutter speed, and the illuminance depends on the lens aperture and the scene luminance. Slower shutter speeds (exposing the medium for a longer period of time), greater lens apertures (admitting more ...

Unlike the coded exposure process, shutter speed is a purely physical process where the camera shutter is opened and closed more quickly, resulting in short exposure time. [5] This reduces the amount of motion that occupies each frame. [6] However shorter exposure times increase the 'noise', which can affect image quality. [7]
Although some photographers (Adams 1981, 66) [1] routinely determined camera settings using the exposure equation, it generally was assumed that doing so would prove too daunting for the casual photographer. The 1942 ASA exposure guide, ASA Z38.2.2-1942, featured a dial calculator, and revisions in 1949 and 1955 used a similar approach.
Exposure can be adjusted by changing either the lens aperture or the exposure time; which one is changed usually depends on the camera's exposure mode. If the mode is aperture priority, exposure compensation changes the exposure time; if the mode is shutter priority, the aperture is changed. If a flash is being used, some cameras will adjust ...
