moving pictures short range apparent motion (formerly “persistence of vision”) The way film came about -- For a long long time, people have wanted to make pictures. And for a long time they have wanted them to move. I don’t know why. But thanks to this great human desire, we have film technology. Early on, people recognized something called “apparent motion” -- that if you put 2 pictures of the same thing next to each other, and flash them one after the other (fix this description), it would appear to be in motion. See experiment What this meant for moving images is illustrated by the flipbook -- if you flash a series of images that are closely related, will give illusion of motion. flipbook

victorian toys thaumatrope zoetrope This led to a bunch of experiments and games -- tarumatrope, zooetrope, etc. Thing to notice with the zoetrope is that when you don’t have the interval of black, just looks like mush. Important for development motion picture technology because the interval is black is what makes the illusion of motion possible -- allows your eye to isolate the frame. So instead of a blur you see one image flashed quickly after another almost identical image. (hold that thought because it relates to the shutter on a projector) zoetrope

Photography - wet plate process1850's Tin Type At the same time, people were trying to capture images that were more realistic than painting or drawing. In the late 1830’s the development of a science of chemistry meant that inventors in England and France were able to use the properties of SILVER NITRATE to create images with light. calotypes, daguerrotypes. Couldn’t reproduce things in motion photographically because of long development time. Ambrotype

Eadweard Muybridge 1872 Forefathers of cinema -- interested in scientistic questions. Eadward Muybridge in California invented a special high-speed shutter and a system of multiple cameras with strings that the horse would trip while galloping. To settle a bet about whether a horse’s feet come off the ground when galloping. Explain how he did it. Considered a forefather of film even though he did it with multiple cameras.

“pan and scan” From Seven Brides for Seven Brothers, MGM, 1954. An example of this is seen in the film Jaws, with the sight of the shark being seen approaching for several seconds more in the widescreen version than in the pan-and-scan version.
