The Language of Light Color Rock formations in the heart of Australia were a place of worship for Aboriginals, because of their seemingly miraculous power to change color. Keep in mind that just as the brightness of sunlight varies throughout the day, so does its color.
Film is more sensitive than the eye in registering changes in the color of light.
Film's response to color is fixed, but the eye adapts to overall shifts in color. Film, on the other hand, records differences in the color of light. These shifts in color can be corrected during printing or, in the case of slide film, by using color correction filters.
