Todd Walker began using the computer to generate images in 1981. He taught himself machine language so he could manipulate his images as he so desired. The first images were video frame grabbed and were printed in the offset, collotype or silkscreen processes. A few prints were done in edition by Nash Editions. Later he used a Fargo Dye Sublimation printer. There are approximately 1000 digital files that span from the 80's through 1998.
