I'm completely addicted to digital drawing. I buy new watercolor paper and traditional paints and pristine sketchbooks at The Art Store, but they gather dust beside my desk. I feel less worthy somehow when I sketch using my computer. Ridiculous, I tell myself -- it's really just like choosing a mechanical pencil over a Berol 2B, or a Rapidograph over a quill pen. No digital god steers my fingers when I sit at my computer. I know that, but somehow I keep planning to get back to "real drawing" someday, where my mistakes aren't permanently erased by a simple "Ctrl-Z" command.
There was that day years ago when a Lt. Gov of Texas stood over my shoulder as I worked inhouse at an educational software company. He watched me maneuver my mouse (yes, we drew with a mouse back then,) coaxing the pixels into the running figure of a child. I was proud and excited as he stood behind me, obviously transfixed at the illustration appearing on the 16 color Tandy monitor. Finally he announced, "I didn't know computers could draw like that!" I guess I still carry that scar.
But. This is how I work.
