Photography and Movies

Abstract

This chapter is mostly about creation, transformation, and preservation of visual information, starting with two-dimensional images of static subjects on paper using photochemistry (photographs) and then photochemical images of moving subjects (movies). This is followed by a brief review of the optical phenomenon of coronal discharge (Kirlian photography), followed by digital cameras, X-ray photography, laser holography, and electron microscopy. These technologies involve using and manipulating light as a carrier of information, involving higher and higher energies (frequencies). The order is roughly chronological in the sense that later technologies depended on the earlier ones.
