Aug., 1944 STEREOPTICON PROJECTOR 99 Obviously the best solution to the problem was to project and rephotograph natural color. To do this required 3 major steps, each in itself a major necessary link in the accomplishment of the whole: (1) The duplication in quantity of correctly distorted, nonfading natural color prints 31/* X 4 in. in size. In this connection, it must be realized that the light source, condensers and optical system, slide glass, and the translucent projection screen used all act as a cumulative filter on the projected image.

(2) The transferring of these duplications to a heat-resisting glass, water clear and free from bubbles or striae, and cemented in a manner to resist the most intense heat without peeling or separating from the glass support and causing Newton-Ring effects during projection. (3) The designing of a unit to project the 31/* X 4-in. image with sufficient light intensity to adequately rephotograph in color.
