Notes:
This photo is an example of tactile plasticity. While the yellow wall is well behind the fence and the orange signs, the yellow areas are so small and de-emphasized that at first glance, they appear to be in the same plane as the fence and signs. Also, the fence and orange signs are both in sharp focus, giving the impression that they are virtually in the same plane. Though the orange does pop towards the viewer more than the black fence and contributes to the tactile plasticity of the photograph, the is more an issue of color theory than tactile plasticity.
