Contributed by Adam Simon / A photographer friend once asked me why painters are always talking about the space in a painting. He wanted to know what this term “space” meant. I talked about the different ways paint on a flat surface could be made to suggest depth, and how the challenge for modern painters was to create depth while also reaffirming the flatness of the support. I probably referred to the elusive concept of the “picture plane” and how simultaneously maintaining mutually exclusive ideas – flatness and depth – could produce a poetic or even a mystical dimension in visual art. Most abstract paintings present shallow space, keeping depth to a minimum. This type of painting is usually non-hierarchical; nothing feels more essential than anything else. The viewer’s eye tends to scan. If you want to both represent depth and reaffirm flatness, shallow space is going to be easier to handle than deep space.
