Mention to most people that light is an element of art and they scratch their heads. Something so obvious as light is easily overlooked, making it almost a hidden tool. When it is highlighted in a piece, you know something special is at play but can't pinpoint what. When discussing light and artists my mind immediatly conjures up the images of Monet's Haystack paintings. Monet was one of the first painters to seriously consider light (and how light changes) when creating art. Others have since tried to manipulate the intangible nature of this element including James Turell, whose work borders civil-engineering or even astronomy a bit more than fine art, who creates what can be described as "installations" of light.
