Echo Location, a multi-media solo exhibition by Colleen Woolpert, reflects how she experienced the former Lee Paper Company mill in Vicksburg, MI with her twin sister Rani Young at the Prairie Ronde Artist Residency in the Summer of 2022. Among her media explorations, Colleen’s stereoscopic photography may be viewed as standard photographs or in 3D for an immersive encounter that predates VR. Colleen’s interest in this format originated with a desire to help her twin sister whose visual impairment (strabismus) impedes her depth perception and affects her mental health. Colleen’s stereoscopes reinforce the vision therapy program that trains Rani’s eyes to coordinate, resulting in depth perception and calm self-confidence. In Colleen’s view, the work is joint art therapy. Support provided by the Kalamazoo Artistic Development Initiative, a program of the Arts Council of Greater Kalamazoo.
