How Does Film Really Work?
The technical term for film is an impression or thin layer, usually a translucent film. An example of film would be a thick layer of paint over the top of some soup. An example of film would be grease over the paint.
There are two standard aspect ratios for stills in use in the US today; the widescreen (wide) and the ratio of 1. Filmmaking frame to screen. These are the accepted standards by the American Film Institute and the Motion Picture Filmographers Association of America. In addition to the aspect ratio, some filmmakers use a Cinema Movie Looks when shooting their films. This is not the same as digital but overlaps some of the qualities of film.
Modern day film cameras capture the image via a complex series of processes beginning with the film negative, which is produced in a lab and processed at a photo shop. The image then goes through several steps, including scanning the negative, which is done digitally, and the copy is made to be reproduced on a print surface. Finally, the image is shown on a monitor, usually by a computer. The creation of a film image is an arduous process.
