'Painting space', or, the amount of space found in a painting. I came up with the term when I started to take reference photographs from locations where I had been painting.
I immediately realized that a single photograph of the location could not capture the entire space I had been creating on my canvas. I had to take many pictures to get the whole scene. Back in the studio I would then cobble them together in photoshop to create a composite, large format image from many single photographs
When putting together multiple shots of a particular landscape through which people had been walking, I realized that I had captured slices of time and could combine them into a single photograph. These are very fun. I call them "Time and Movement."
