ComS 27a and 27b Lecture and Lab Scope of the course About the Professor
3
3 Camera&Eye The eye gathers patterns of reflected light which the brain translates into images we see Still Film Cameras record light patterns on film coated with light sensitive chemicals Convex lenses (curved outwards) invert images The brain and cameras turn images right side up again
4
4 Movie Cameras Record images in the same way as still film cameras they just do it more often Eight mm: 18 fps 16 and 35mm cameras take 24 fps When pictures are projected onscreen they give the illusion of continuous motion
5
5 Persistence of Vision The viewer’s mind fills in the gaps between the individual frames due to this physiological phenomenon
6
6 Digital Cameras (still and video) Lens focuses light patterns onto a light- sensitive surface made up of small flat chips called CCDs Each CCD contains thousands of tiny light- sensitive areas (pixels) which change according to the color and intensity of the light hitting them
7
7 Video Cameras Convert Light Patterns into Electronic Images Images are electronically collected off the chip at the rate of 25-30 fps At the viewfinder or TV set the process is reversed to recreate the original image Persistence of vision causes the viewer to perceive the separate pictures or frames as continuous movement.
8
8 Exposure Amount of light that comes through the lens and hits the film or CCD chip The hole in the center of the lens that the light travels through is the aperture F 2 means that the aperture is 1/2 as big across as the lens is long--16 is 1/16 1 stop lets in twice as much or 1/2 the light

DV and HDV vs. 8mm VHS Better screen resolution Color fidelity Reduced video artifacts
10
DV vs. Film Enables an “appalling lack of discipline” on the part of the shooter. Not enough financial penalty for shooting poorly The expensive 16mm documentary has gone away
11
5 C’s of Cinematography Camera angles Continuity Cutting Close-ups Composition

Film Costs from Yale Labs http://www.yalefilmandv ideo.com/ http://www.yalefilmandv ideo.com/ 100’ = about 3 minutes
13
Experts? F-stops Shutter speeds Film emulsions Incident vs reflected Now you have to do it all! And not for much money!
14
Penalty for Lack of Discipline? Need to tell a compelling visual story Adequate coverage: “the range of shots necessary to assemble a finished show” A successful shooter edits as she/he is shooting Truckloads of tape and editing
15
15 Color Temperature Color films and ccd chips can only handle only one color of light Color filters are used to convert the existing light to the color temperature required 15
