The Board Used Instead of a Tripod is Placed across the Backs of Two Car Seats
Some form of a roll-film camera is essential, and simply as a working basis, it will be assumed an ordinary camera is used, post-card camera in size, for which the following things will be required: A piece of thin black card, or hard rubber; a small board, and a piece of wire to be used as a crank.
These Two Articles Constitute the Only Parts Necessary to Change a Camera into a Mile-O-View
Prepare the paper, or hard rubber, by cutting it to a size that will exactly cover the rear camera opening when the back of the camera is removed, which, in the case of a post-card size, is 6 in. long and 3-3/4 in. wide; then cut a narrow slot, about 3/64 in. wide crosswise through the center of the material. This slot should extend to within about 1/2 in. of each edge, and the edges must be perfectly smooth and straight. If paper is used, glue it to the opening in the camera. If hard rubber is used, it can be made up as shown and set in the camera opening. This will bring the slot directly back of the lens center and at right angles to the direction in which the film moves when being rolled.
The Two Parts as They are Applied to an Ordinary Roll-Film Camera
A board is prepared, about 4 ft. long, 10 in. wide and 3/4 in. thick. This is to take the place of a tripod, and it must have a small hole and suitable wing nut to attach the camera near the center. This length of board will reach from the back of one seat to another when it is placed to support the camera during the exposure.
A wire, about 1/8 in. in diameter, is bent, as shown, with a short hook on one end, and the other turned up at right angles, to serve as a handle. This wire, when hooked into the wing nut, will enable one to wind up the film at a fairly uniform speed. This completes all the necessary apparatus.
