[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.
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 ...
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
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 ...

Photographs meant to accurately describe otherwise unknown, hidden, forbidden, or difficult-to-access places or circumstances date to the earliest daguerreotype and calotype "surveys" of the ruins of the Near East, Egypt ...
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 ...
Many variables affect the sequence of scenes as they are arranged and rearranged on a strip board. Outdoor scenes subject to fickle weather conditions [2] [9] and difficult stunts and special effects are sometimes scheduled early in principal photography, so there is time to recover and make necessary changes if problems arise. [6]
The model was lit on the left with a strobe.The light was warmed with an orange gel to match the sunset. Photographic lighting refers to how a light source, artificial or natural, illuminates the scene or subject that is photographed; put simply, it is lighting in regards to photography.
