    • 1. EMC / JOUR 3000INTRO TO MOTION PICTURES Edward BowenLecture One - The Technical Dimension, Part 1
    • 2. Technology of Motion PicturesCamera Obscura• Take a big box into the sunlight.• Get inside.• Cut a small hole in one side.• Stand clear.• On the side opposite the hole you will see an image (reversed and upside down) of whats outside.• You are in a camera obscura.• Put a piece of film where the image is and expose it.• You are now in a camera.

    • 6. Technology of Motion PicturesPersistence of VisionThe concept that the eye retains one image just long enough to blend it with a following image.This permits a sequence of still pictures to appear as one continuous action.Physiologists and neurologists have developed revised theories for how we perceive motion (Beta Movement, Phi Phenomenon).The theory of “persistence of vision” still retains popular acceptance.

    • 10. Technology of Motion PicturesFilmOne medium on which motion picture images are recorded.Film is composed of many layers, two of whichare• a base, and• emulsion.
    • 11. Technology of Motion PicturesFilm Base – Cellulose, a synthetic plastic invented around 1870.• Cellulose Nitrate, or Nitrate Film• Cellulose Acetate, or Safety Film
    • 12. Technology of Motion PicturesFilm Base• Cellulose Nitrate, or Nitrate Film• Unstable• Highly flammable
    • 13. Technology of Motion PicturesFilm Base• Cellulose Nitrate, or Nitrate Film• Unstable• Highly flammable• Made illegal in 1949
    • 14. Technology of Motion PicturesFilm is not a permanent medium.About 80% of films made before 1920 no longer exist.About 50% of films made before 1950 no longer exist.
    • 15. Technology of Motion PicturesFilm EmulsionThe layer of photo-sensitive chemicals that coats the film base
    • 16. Technology of Motion Pictures Film Emulsion The layer of photo-sensitive chemicals (silver halide) that coats the film basehttp://www.youtube.com/watch?v=yJ5bf_GEW_o
    • 17. Technology of Motion PicturesFilm Emulsion• Black and White – A single chemical layer renders only shades from black to white
    • 18. Technology of Motion PicturesFilm Emulsion• Black and White
    • 19. Technology of Motion PicturesFilm Emulsion• Black and White• Color – Comprised of three layers of emulsion: yellow, magenta, and cyan. Combined they render full color

    • 48. Technology of Motion PicturesHD Digital VideoAnother medium on which motion picture images are recorded.Digital cinematography cameras capture images using CMOS or CCD sensors.Information is stored on magnetic tape or as digital files onto random-access media like optical discs, hard disk drives or flash memory-based digital “magazines.”

    • 51. Technology of Motion PicturesFrame. A single photograph in a series that comprise a motion image.
    • 52. Technology of Motion PicturesAspect ratio: The relationship of the width of the image tothe height of the image.Standard or Academy ratio (4 X 3 or 1.33:1). In adoptingthe 35 mm format early filmmakers established thestandard aspect ratio as a classical rectangle with a ratioof four units of width to three units of height. Thus if theprojected image is twenty feet wide it will be fifteen feethigh.
    • 53. Technology of Motion PicturesAspect ratio: The relationship of the width of the imageto the height of the image.Widescreen (1.66:1;1.85:1; 2.35:1). Over the years manyfilmmakers (Lumière, Griffith, Gance, etc.) experimented withthe widescreen. Gance’s system, for example, employedthree regular-sized screens, producing an effective aspectratio of 3.99:1. Efforts to introduce widescreen technologywere not successful until the 1950s when cinema tried tocounter program against television. Some of the 1950swidescreens had a ratio of as much as 2.66:1(CinemaScope). An image 26.6 feet wide and ten feet tallmade for some strange closeups! The American standardwidescreen ratio was finally set at 1.85:1. (The Europeanstandard widescreen ratio is 1:66:1.) Wider ratios areavailable through the use of anamorphic lens systems(2:35:1) and 70 mm film (2.2:1). IMAX and movie rides areanother matter, with domed and curved screens that defy the

    • 70. Technology of Motion Pictures3D - Creating the illusion of depth by photographing two images simultaneously, one for the viewer’s right eye and one for the left, then projecting or displaying them in such a fashion that each eye sees only one of the images. The brain then “thinks” it sees three dimensions.
