Value is determined by the relative lightness and darkness of a surface. When the complete scale of value is used shapes start to look three-dimensional. The use of value also helps one perceive that there is more space than is actually there. Many artists use value in their paintings to give their piece more definition and tension. With the use of value it increases the space perceived in a composition or it can help accentuate an object even more. In Thomas Moran’s piece “Noon day rest in Marble Canyon” he utilizes the full range of value. In this landscape piece Moran depicts the boat in the foreground with his darker use of value. The rocks in the extreme foreground are in an even darker shade of black than the boat. Along with the cliff in the middle ground to give it the impression that it is in the middle to foreground, it is as depicted in a much darker shade than the other items in the piece. How Moran gives the illusion hat the water, cliffs, and rocks seem to be going back in space is by using a whiter value on the value scale. With the use of a lighter gray the images look as if they are blurry and thus receding in space. In this composition Moran does an excellent job at utilizing the entire value scale.
