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.
For daylight photography, there is a similar rule called the Sunny 16 rule. The basic rule is: "For astronomical photos of the Moon's surface, set aperture to f /11 and shutter speed to the [reciprocal of the] ISO film speed [or ISO setting]." [1] With ISO 100, the photographer should set the shutter speed to 1/100 or 1/125 second.
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 ...
The sunny 16 rule can be used in varying light by setting the shutter speed nearest to the ISO film speed and f-number according to a generalized exposure table, as: [3] [4] Tessina with exposure guide plate from the 1960s. At that time, DIN 21 was equivalent to ASA 80. After 1983, DIN 21 was ASA 100. [5]
A 30-minute photo of a static object and surrounding cannot be distinguished from a short exposure; hence, the inclusion of motion is the main factor to add intrigue to long exposure photos. Images with exposure times of several minutes also tend to make moving people or dark objects disappear (because they are in any one spot for only a ...

Typical exposure times range from 15 minutes to many hours long, depending on the desired length of the star trail arcs for the image. [7] Even though star trail pictures are created under low-light conditions, long exposure times allow fast films, such as ISO 200 and ISO 400. [6] Wide-apertures, such as f/5.6 and f/4, are recommended for star ...
