Lighting determines exposure and can be used to create effects such as low-key and high-key lighting, both of which involve the contrast between darker and lighter elements in a scene. [2] Lighting is especially important for monochrome photography, where there is limited to no color information, and exclusively includes the interplay of ...
The streetlight effect, or the drunkard's search principle, is a type of observational bias that occurs when people only search for something where it is easiest to look. [1] Both names refer to a well-known joke: A policeman sees a drunk man searching for something under a streetlight and asks what the drunk has lost.
Generally, the technology of digital photography extended the range for available light photography strongly. While it is possible to make decent images of night scenes in streets or in rooms without flash even with the cameras of standard smartphones of 2022, this was virtually impossible with the former photographic film , with the only ...
Analog photography, also known as film photography, is a term usually applied to photography that uses chemical processes to capture an image, typically on paper, film or a hard plate. These processes were the only methods available to photographers for more than a century prior to the invention of digital photography , which uses electronic ...
An important difference between digital and chemical photography is that chemical photography resists photo manipulation because it involves film and photographic paper, while digital imaging is a highly manipulative medium. This difference allows for a degree of image post-processing that is comparatively difficult in film-based photography ...
Otherwise, energy not only could be wasted but over-illumination can lead to adverse health and psychological effects. Beyond the energy factors being considered, it is important not to over-design illumination, lest adverse health effects such as headache frequency, stress, and increased blood pressure be induced by the higher lighting levels ...
Optical effects (also called photographic effects) are techniques in which images or film frames are created photographically, either "in-camera" using multiple exposures, mattes, or the Schüfftan process or in post-production using an optical printer. An optical effect might place actors or sets against a different background.
A street light, light pole, lamp pole, lamppost, streetlamp, light standard, or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform.
