Looking at Movies: Chapter 11


Terms in this set (...)

film is this medium in which it creates an image by recording through a camera lens the original light given off by the subject and stores this image on a roll of negative film stock
first stage of filmmaking
the camera exposes film to light allowing radiant energy to burn a negative image onto each frame
these single, discrete images are shot standard (for theatrical movies anyway) 24 frames per second
the second stage, the negative is developed into a positive print that the filmmaker can then screen in order to plan the editing, a process that produces the final print
in the third stage, the final print is run through a projector, which shoots through the film a beam of light intense enough to reverse the initial process and project large image on the movie screen
traditionally 16 frames per second for a silent film and 24 fps for sound-creates an illusion of movement
silent cameras and projectors were often hand cranked
cameras and projectors used for making and exhibiting professional films are powered by electric motors that ensure perfect movement of the film
as the digital technology replaces the mechanical process, it is changing the equipment and media on which the images are captured, processed, and projected
but the role of light remains the same essential component
is the gauge, or width of the film stock, and its perforations (measured in millimeters) and the size and shape of the image frame as seen on the screen
film-stock length
is the number of feet (or meters) of the number of reels being used in a particular film
film-stock speed
or exposure index indicates the degree to which the film is light sensitive. this speed ranges from very fast, at which the film requires little light, to very slow, at which it requires a lot of light
the length of time that the film is exposed to light
the capacity of the camera lens, film stock, and processing to provide fine detail in an image
digital technology
involves an electronic process that creates its images through a numbered system of pixels (which we can think of as the binary-two parts numbers of 0 and 1)
unlike analog images, these images do not have a physical relationship to the original.
they are not exactly images, but rather thousands of digits stored on a flash card or a computer hard drive
the first stage
consists of planning and preparation
takes usually a year or two
the actual shooting
can last six weeks to several months or more
consists of three phases: editing, preparing the final print, and bringing the film to the public (marketing and distribution)
