The Visual Process
It would be difficult to find a more cogent confrontation between physics and biology than in the visual process. Nature was faced from the beginning with the hard fact that light consists of a finite number of bits of energy, called “photons” or “quanta.” Whatever visual information was to be distilled out of the surrounding world was circumscribed by the profound constraints imposed by the discrete nature of light.

The authors find that the signal-to-noise ratio of a studio television picture exceeds that of 16-mm, color reversal film, ASA-125. Many of the 16-mm film clips used on television are significantly noisier than the color film used by these authors.Google Scholar
