Unfortunately, we have not had opportunity to photograph any very romantic subjects, and the pictures illustrated are those of white numbers painted on a black belt moving across the object field. Fig. 6 shows a reproduction of one frame from the 16-mm motion pictures we have taken of the viewing grid being motor driven across the exposed developed plate. The numbers are quite identifiable even in cases where the images are moving as fast as 250 miles per hour on the plate. In Fig. 7 we have stopped the translation of the grid in a mid-point of image travel. The number aspect you see is the result of a small amount of rotation of the grid analyzer. This rotation allows you to see an early time picture of the tops of the numbers and a late time picture of the bottoms of the numbers. The numbers slant from left to right, As the analyzing grid becomes parallel to the taking grid position, the numbers straighten up as in Fig. 6 because the top of the numbers was taken at the same time as the bottom of the numbers. Finally, as the rotation of the grid is reversed, the numbers lean from right to left as in Fig. 8 because you are seeing the late time picture of the tops of the numbers and an early time picture of the bottoms of the numbers.
