. . . Those commonplace and merely 'beautiful' pictures, which thrive mainly thanks to the charms of some actual object, are thrust into the background in favor of experiments and fresh solutions. Adventures into the realm of optics are still for the most part unpopular. But only that photography which enlists the help of the experimental will be able to lay bare al the technical and creative possibilities that are proper to the formation of the visual experience of our times.

— Otto Steinert, 1951
