Exploring the Spectrum: The Effects of Natural and Artificial Light on Living Organisms (1975)

An exciting video journey through the world of time-lapse photography by one of the founders of the science of photobiology. Do fluorescent lights cause cancer and childhood learning and behavior disorders? Can long-term exposure to low-level radiation as from TV sets, computers, fluorescent lights, and similar devices harm your health? Does living behind window glass and with glasses covering our eyes over years affect our health? Is natural sunlight and trace ultra-violet radiation really harmful to our health? Or is it necessary and beneficial? How do cells, plants and animals respond to constant exposure to different light color frequencies? Does mal-illumination and electrosmog create nervous agitation and a weakened immune system? These and similar questions were the subject of Dr. John Nash Ott's pioneering investigations in the field of photobiology, using the methods of time-lapse photography.
