Unlike painting, in sculpture, the perception of spatial depth may be the most important thing to consider. The relationship of each of the elements distributed in the space is the real challenge to take into account in creating sculpture. In the vast majority of cases, color is dispensed with to focus attention on three-dimensional shapes. In a traditional two-dimensional photograph of a sculpture that perception of depth is lost, and therefore two-dimensional photography is a very ineffective means to represent the spatial awareness of a sculpture.
