However, the main disadvantage is still the film's very slow exposure, requiring hours of exposure time. This means that currently this type of film can be used only in ultra-long-exposure film photography where the subject is e.g. a city center where the photographer wants to fade all movement. [62]
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 ...

The science of photography is the use of chemistry and physics in all aspects of photography. This applies to the camera, its lenses, physical operation of the camera, electronic camera internals, and the process of developing film in order to take and develop pictures properly.
Cinematographers may also apply exposure compensation for changes in shutter angle or film speed (as exposure index), among other factors. Many digital cameras have a display setting and possibly a physical dial whereby the photographer can set the camera to either over or under expose the subject by up to three f-stops ( f-numbers ) in 1/3 ...
Once the film was developed it was sliced down the middle and the ends attached, giving 50-foot (15 m) of Standard 8 film from a spool of 25-foot (7.6 m) of 16 mm film. 16 mm cameras, mechanically similar to the smaller format models, were also used in home movie making but were more usually the tools of semi professional film and news film makers.
A frame from Roundhay Garden Scene, the world's earliest surviving film produced using a motion picture camera, by Louis Le Prince, 1888. A film, also called a movie, motion picture or moving picture, is a work of visual art used to simulate experiences that communicate ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images.
Initially, a lack of standardization meant that film producers used a variety of different film widths and projection speeds, but after a few years the 35-mm wide Edison film, and the 16-frames-per-second projection speed of the Lumière Cinématographe became the standard.
