Example of a low-key photograph. Low-key photography is a genre of photography consisting of shooting dark-colored scenes by lowering or dimming the "key" or front light illuminating the scene (low-key lighting), and emphasizing natural [1] or artificial light [2] only on specific areas in the frame. [3]
This camera is lit by a soft box positioned above, with a white reflector to the front-left. Low-key lighting is a style of lighting for photography, film or television. It is a necessary element in creating a chiaroscuro effect. [1] Traditional photographic lighting (three-point lighting) uses a key light, a fill light and a back light for
Sometimes, as in low-key lighting, this is a deliberate effect, but shots intended to look more natural and less stylistic require a fill. In some situations a photographer can use a reflector (such as a piece of white cardstock mounted off-camera, or even a white-painted wall) as a fill light instead of an actual lamp.
A CCD (Charge-Coupled Device) imager provides a low-noise analog image signal, which is digitized when used in a digital camera. For their contribution to digital photography, Boyle and Smith were awarded the Nobel Prize for Physics in 2009. [2] In 1973, Fairchild developed a 100 x 100 pixel interline CCD image sensor. [3]
The three light setup is a common method used in photography. This method uses three separate lighting positions to give the photographer a great deal of control in illuminating the subject. It is formed by a main light known as the "key", the fill light, and the backlight. [4]
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.
Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure 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 .
The key light can be "hard" (focused) or "soft" (), and depending on the desired setup can be placed at different angles relative to the subject.When part of the most common setup—three-point lighting—the key light is placed at a 30–60° angle (with the camera marking 0°).
