Night photography (also called nighttime photography) is the capturing of images outdoors between dusk and dawn. Night photographers generally have a choice between using artificial lighting and using a long exposure , exposing the shot for seconds, minutes, or hours in order to capture enough light to record an image.
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 ...
Looney 11 exposure of the Moon - 1/200 second, ISO 200, f /11. In lunar photography, the Looney 11 rule (also known as the Looney f /11 rule) is a method of estimating correct exposures without a light meter. For daylight photography, there is a similar rule called the Sunny 16 rule.
In photography, the metering mode refers to the way in which a camera determines exposure. Cameras generally allow the user to select between spot, center-weighted average, or multi-zone metering modes. The different metering modes allow the user to select the most appropriate one for use in a variety of lighting conditions.
Proper use of tabulated exposure values is explained in detail in the ANSI exposure guide, ANSI PH2.7-1986. The exposure values in Table 2 are for ISO 100 speed ("EV 100 "). For a different ISO speed S {\displaystyle S} , increase the exposure values (decrease the exposures) by the number of exposure steps by which that speed is greater than ...
In digital photography, exposing to the right (ETTR) is the technique of adjusting the exposure of an image as high as possible at base ISO (without causing unwanted saturation) to collect the maximum amount of light and thus get the optimum performance out of the digital image sensor.

Starting 1954, the so-called Exposure Value Scale (EVS), originally known as Light Value Scale (LVS), was adopted by Rollei, Hasselblad, Voigtländer, Braun, Kodak, Seikosha, Aires, Konica, Olympus, Ricoh and others, introducing lenses with coupled shutters and apertures, such that, after setting the exposure value, adjusting either the shutter ...
