Nothing: Real. Deep. was a collaborative installation with Dr. Adam J. Graves that superimposed stereoscopic imaging and relief cartographical techniques in order to invite viewers to explore themselves as viewers. Historically, both techniques have been variously employed for the purposes of virtually re-presenting spatial depth through two-dimensional media—in the early nineteenth century, the British Raj used the latter to capture the elevation of the Himalayas in its Great Trigonometric Survey of India, while stereoscopic photography became popular around the same time as means for creating a life-like experiences of exotic or far-off locations. This effort to represent a “truer” image of a place by producing the illusion of space, or to make space itself appear, was achieved, at least in part, by making the viewer explicitly aware of the act of perceiving itself. This increased level of self-consciousness regarding the conditions surrounding the act of seeing is also a distinctive feature of viewing art objects, and is a natural consequence of the art gallery setting. By inviting viewers to walk through the space of the gallery and dwell momentarily among its objects, the art of capturing the invisibility of space becomes itself part of the illusion—not the illusion of depth, but rather the depth of illusion.
