One way to look at a photograph is to look for depth. The ability to convey depth on a flat plane is often considered one of the standard factors for evaluating a work. Thus, among photographers, much is written about how to create this illusion. Discussions abound about depth of field, selective focus, aperture, using multiple objects diminishing in size in the distance, converging parallel lines.
However, I find the opposite approach equally interesting: to see a reality with depth and portray it as a flat plane, as if it had no depth at all, as if it were an abstract expressionist painting. For example, Calle Empedrado La Habana Vieja; or Pershing Square Los Angeles, Women’s March January, 1917.
