This photo by Jon Baez is a prime example of perspective, depth, and space. It is a depiction of the under supports of a bridge. The way the waning sunlight is a gradient across each beam, with the light concentrated at the closest and highest beam, down to the dimmest light at the furthest and lowest beam, creates a sense of depth and moody space. The gradient of light across each beam not only shows perspective, it also is very visually striking.
Lovely photo and good description.
