My investigation of the visual field concerns the process of focus by which we explore it; I've used video as a way to recreate the flow of perceptual awareness that generates our impression of a unified visual field. In the process I consider the video itself a sort of surrogate for my own body and its spatial awareness. Given that much of the visual field is actually "not seen" in our process of constantly shifting focus, I use color, observed on site and generated in the studio, to lend it material presence.These color grids can function as frames, which enable me to focus on selected visual sensations in drawing, or to select an area to represent the visual field as a whole. I'm intrigued by the "overall" field, even as I know it is unrepresentable.
