Light in photography is a vast theme, described in countless publications and articles. Any given photograph or image may be analysed from the perspective of light. Thanks to light, we are able to see, take pictures, but also look at them. The history of photography, closely tied to scientific and technological progress, is specifically permeated with technological struggles related to registration of light. It is a history of attempts to ‘tame’ it, to record an image in the shortest time possible, or to create artificial conditions that will enable photographing despite its lack.
