Contrast

Big Fall, Black and White by Pat Steir.  I selected this image for the obvious.  The black background gives the presences of absences while the white is the perfect contrast to give the image life.  Due to void of the black the white water stands out even more since there are no primary colors in the image.  Even with the absence of color you ca still see the details in the water fall as a whole.  The drops of water on the perimeter add the the overall contrast against the black background.
