How Light Works
“Mere color, unspoiled by meaning, and unallied with definite form, can speak to the soul in a thousand different ways.”
Oscar Wilde
This image was made on Ektachrome 200 film with a Nikon F3 camera equipped with a Nikkor 105mm f2.8 Macro lens. Using a 12 inch in diameter 8ft. focal length circular parabolic mirror placed exactly 8ft. from the film plane of the camera which was mounted on a tripod, I taped a Vivitar 283 flash opened and laid flat to the top of the lens so that the light would go directly into the mirror and be reflected into the lens. Using a gridded focusing screen to precisely place the three circles (mirror) in the frame, I made three separate exposures on the same frame of film; one with a #25 red filter, another with a #47B blue filter and the third with a #58 green filter carefully overlapping the three circles so that the three primary colors (red, green and blue) would produce their complementary colors (cyan-complement of red, magenta-complement of green and yellow-complement of blue). Where all three overlap it is white, as white light is composed of red, green and blue light.
