A motion picture camera is a device that is capable of capturing a series of images in sequence at a high speed, giving the illusion of motion when played back.
The first film camera was designed by Louis Prince in 1888, the first movies frame rate was 14/20 frames per second. This is because they were hand cranked cameras.
Experimentations were made with digital cameras by the BBC, using cathode ray
tubes, this was in the 1930's.
Kodak launched 16mm film stock for lots of cameras, as a cheaper cost alternative then 35mm in 1923 This was used by many amateur filmmakers.
Most colour cameras
came about in the 50’s and 60’s, also The development of storing information changed
drastically over the years and camera's became smaller and more compact.
The current industry film standard is 35mm, which depends on quality, This can range
between 10-24 megapixels or higher.
The current industry digital standard is 4k which is 12 megapixels on the other hand, some films
are currently being shot at 6k (19 megapixels)
this is an example of HD compared to 4k.
The shutter opens,
and light travels through the lens, exposing the film or sensor
After this the shutter closes,
and the next piece of unexposed film moves into place.
DSLR’s like below
have made such a huge impact on the film industry because the
sensor size of a
digital camera has a big impact on the look
and quality of an image, This has allowed affordable film making.
The general rule of
sensors are..
If it’s larger, it
will produce better quality mages, and handle dark situations much
better,
However If it’s small, it will have a higher frame rate capability, but produce more grain in darker situations.
There are three main
functions of controlling the way an image is
exposed correctly
with a camera :
Shutter Speed (How
quickly
an image is captured)
Aperture (Controls DoF)
ISO (Sensitivity)
