visual perception in darkness
Saskia & Pim choose to reseach ‘night vision’, an invention of William Edward Spicer -engineering professor at Stanford University-, being first used by the U.S. Army during WW2.
Night vision is the ability to see in a dark environment. Whether by biological or technological means, night vision is made possible by a combination of two approaches: sufficient spectral range, and sufficient intensity range. Humans have poor night vision compared to many animals, in part because the human eye lacks a tapetum lucidum.
Following McLuhan’s tetrad: night vision devices do not enhance really; instead they add a visual quality. It makes electric light obsolete and pushed to extremes one’s biorhythm can be disturbed due the absence of day and life. The medium probably retrieves the yearning for ‘normal’, polychrome perception with the bare eye.
