808.6 (B) Film Format

Film is a thin sheet or strip of flexible cellulose coated with a photosensitive emulsion. When the emulsion is sufficiently exposed to light it forms a latent image. Chemical processes can be applied to the film to create a visible image. The series of still images are then run through a projector and shown on a screen, creating the illusion of moving images. Films usually include an optical soundtrack, which is a visual representation of the sound waves for the spoken words, music, and other sounds intended to accompany the images. The soundtrack is located on a portion of the film that is not projected on the screen.
