Photography and the four dimensions

By Dr. Jiménez

Photography is the only art where each and every one of the four dimensions take part. In the diagram above, figure a. represents an hourglass in the three dimensions. Its image in the form of parallel rays of light (fig. c.) passes through a convex lens (fig. d.), converging at a focal point into one dimension (fig. f.). At the precise moment in time (b.) or fourth dimension, a exposure is taken resulting in an inverted two-dimensional photograph (fig. g.)
