ANIMATION DATA
By Dr. Charles W. Bethune
Illustrated By The Author
ALMOST any amateur movie camera can be used to make animated pictures. First, a frame must be constructed to hold the camera rigidly in a vertical position. This is shown in drawing A. This frame, similar to a saw-horse or trestle, is called a quadripod. Then secure a kitchen table and 14x17 Eastman X-ray Viewing Box (Eastman because the frame is made of wood; all others that I am familiar with are of metal). Cut a hole in the center of the table slightly larger than the top of the sheet metal reflector of the viewing box. Remove the triangular feet from frame; set the box in the hole, and secure the frame to the table top by a couple of screws. Bore two 3/16" holes on the long side of the frame eleven inches apart, and set a peg in each, securing it with a drop of glue. For illumination use a FLAT 400 watt projector

globe. The vertical type will not give even illumination. Next secure 11x14 sheets of celluloid. Old X-ray films, cleansed of emulsion by soaking in hot strong solution of carbonate of soda and scrubbing with a stiff brush, are excellent. If one likes to smoke while working it is wise to use safety film stock, because the ordinary films are very inflammable.
With a 3/16" harness punch, punch holes in the long side of films to match the pegs.
To draw on celluloid, rub surface
gently with fine steel wool to get a tooth to the surface. Use Higgins yellow label general drawing ink. It is water soluble and can be washed off with a damp sponge. The white label ink is indelible. As to pens, use a stub to get a broad line. If one is not an adept at drawing, pictures can be traced. Many of the pictures in a child's drawing book make fine animated pictures. If the picture is too large or too small it can easily be copied the correct size. The individual pictures are on the screen but a fraction of a second, and consequently do not have to be as carefully drawn as a still. The animation is what counts.
Taking the picture of the lady washing clothes, the first figure is the basic film, which contains all the background and other parts of the view which do not move. Trace this first, then place blank film on pegs
