Many of the paintings and drawings you see here begin as small sketchbook paintings (you can usually see the crease in the book as a giveaway sign). I like that small format. Then I photograph them and make some edits. The result is often pleasingly surprising and can result in multiple versions of a source work. I suppose it's no different than straight photography. I see something in the world that prompts a response and make an image of it. With the painting/photos it's the same -- I see the source painting I've created and then photograph it.
So, while I maintain separate galleries for paintings/drawings and photographs, they all begin from the same impulse. Both processes are satisfying.
