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.
The film's finale was created with mechanically controlled slit-scan photography, which required precise camera motion control during the exposure of single frames. The first large-scale application of motion control was in Star Wars (1977), where a digitally controlled camera known as the Dykstraflex performed complex and repeatable motions ...
In some cases, ambient light may be used as a fill, in which case additional lighting provides the stronger light source, for example in bounce flash photography. The relative intensity of ambient light and fill light is known as the lighting ratio , an important factor in calculating contrast in the finished image.
A skilled photographer can manipulate how a viewer is likely to react to the content of a photo by manipulating the lighting. [6] When shooting outdoors, changing locations may be required, as well as waiting for the ideal time of day (or even the ideal time of year in some cases) for the lighting to create the desired impression in the photo.
For example, prosthetic makeup can be used to make an actor look like a non-human creature. 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 ...
Agfacolor. Ap-41 process (pre-1978 Agfa color slides; 1978-1983 was a transition period when Agfa slowly changed their color slide films from AP-41 to E6); Anthotype; Autochrome Lumière, 1903
A miniature effect is a special effect created for motion pictures and television programs using scale models. Scale models are often combined with high speed photography or matte shots to make gravitational and other effects appear convincing to the viewer.
With the proliferation of particular genres, film subgenres can also emerge: the legal drama, for example, is a sub-genre of drama that includes courtroom- and trial-focused films. Subgenres are often a mixture of two separate genres; genres can also merge with seemingly unrelated ones to form hybrid genres , where popular combinations include ...
