  2. Long-exposure photography - Wikipedia

    en.wikipedia.org/wiki/Long-exposure_photography

    Long-exposure photograph of a break in pool. Long-exposure, time-exposure, or slow-shutter photography involves using a long-duration shutter speed to sharply capture the stationary elements of images while blurring, smearing, or obscuring the moving elements. Long-exposure photography captures one element that conventional photography does not ...

  3. Sunny 16 rule - Wikipedia

    en.wikipedia.org/wiki/Sunny_16_rule

    Sunny 16 rule. In photography, the sunny 16 rule (also known as the sunny f/16 rule) is a method of estimating correct daylight exposures without a light meter. Apart from the advantage of independence from a light meter, the sunny 16 rule can also aid in achieving correct exposure of difficult subjects. As the rule is based on incident light ...

  4. Exposure value - Wikipedia

    en.wikipedia.org/wiki/Exposure_value

    Exposure 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 [2] 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.

  5. Exposure (photography) - Wikipedia

    en.wikipedia.org/wiki/Exposure_(photography)

    Exposure (photography) Photographic image taken using a variety of exposures. In photography, exposure is the amount of light per unit area reaching a frame of photographic film or the surface of an electronic image sensor. It is determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in units of lux - seconds ...

  6. Shutter speed - Wikipedia

    en.wikipedia.org/wiki/Shutter_speed

    The shutter speed dial of a Nikkormat EL Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. 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 ...

  7. Looney 11 rule - Wikipedia

    en.wikipedia.org/wiki/Looney_11_rule

    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.

  8. Night photography - Wikipedia

    en.wikipedia.org/wiki/Night_photography

    Night photography (also called nighttime photography) refers to the activity of capturing images outdoors at night, 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 even hours in order to give photosensitive film or an ...

  9. Shutter (photography) - Wikipedia

    en.wikipedia.org/wiki/Shutter_(photography)

    Shutter (photography) In photography, a shutter is a device that allows light to pass for a determined period, exposing photographic film or a photosensitive digital sensor to light in order to capture a permanent image of a scene. A shutter can also be used to allow pulses of light to pass outwards, as seen in a movie projector or a signal lamp.
