The degree of overexposure depends on the film and the camera used, as well as their different dynamic features. [7] These characteristics are particularly important for portrait photography, in which an extra flash is often used to balance the light on the face or other parts of the body and to soften contrasting shadows in order to properly ...
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.
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]
In lighting design, backlighting is the process of illuminating the subject from the back. In other words, the lighting instrument and the viewer face each other, with the subject in between. This creates a glowing effect on the edges of the subject, [1] while other areas are darker. The backlight can be a natural or artificial source of light.
In photography, reciprocity refers to the relationship whereby the total light energy – proportional to the total exposure, the product of the light intensity and exposure time, controlled by aperture and shutter speed, respectively – determines the effect of the light on the film. That is, an increase of brightness by a certain factor is ...
With color film or video, a graduated neutral-density filter can achieve a similar effect, as can a polarizing filter. Using either of these filters can limit camera movement during a shot, as the axis of a graduated filter must match the horizon, and the effect of the polarizing filter changes as the axis of the camera lens moves relative to ...

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.
