Without light, there is no colour. Orangey flames reveal a fire’s power, while the blueish shadows of a full moon soften the landscape. Whether it emanates from the sun or Edison’s bulb, light awakens our senses and its effects shine into the very core of our being. We feel a divine presence when rays stream through the clouds and we are moved by the ephemeral spectacle of the fluorescent aurora borealis. Light transforms as hours and seasons pass; it amplifies contrasts and alters atmospheres. During the day and at night, light waves influence the eye and change our visual perception. What about you? Which light do you prefer? Big city brightness or countryside starlight? Are you afraid of the dark?
