Object Specific Text

The TwinScope Viewer is both an art object and technically-refined stereoscope, used for exhibiting stereographs or viewing them hand-held. I originally designed it to solve the problem of displaying my own contemporary stereographs, but was soon making them for others as well. David Broda's TwinScope Viewer from 2013 was one of the first that I produced, and was my gift to him as a friend and fellow stereo photography enthusiast/artist. The rubber eye cups were cast by Mike Giannattasio, before I learned to do the process myself. As an early example, Dave Broda's is rough but special because it represents the project's development at that time (note: it is not suitable for hanging as it lacks the custom hanging bracket and integrated hardware). In 2014, I produced and curated "SLIDE: Polaroid Stereographs by Dave Broda" at the SALTQuarters Gallery in Syracuse, New York; Dave's engaging polaroid pairs were presented in matts with TwinScope Viewers hanging below, which brought the 3D images to life for visitors. Today, I make the TwinScope Viewer for collectors and institutions internationally. The patent process was also something of an art project, linking ideas of invention and art production. It was granted in 2018.

Colleen Woolpert explores the meaning of vision—from visual perception itself to abstract concepts like imagination, wonder, and doubt. Motivated by her foundational experiences as an identical twin whose sister lacks depth perception, her interdisciplinary projects have involved a reappraisal of stereographs, collaborations with blind artists, and becoming an inventor. She has received grants from the New York State Council on the Arts (NYSCA); exhibited at the Smithsonian Archives of American Art, Griffin Museum of Photography, and Schneider Gallery, among other venues; and holds a patent for her handmade exhibition stereoscope, the TwinScope Viewer, acquired internationally by collectors and institutions including the Smithsonian National Museum of Natural History and Stiftelsen Lillehammer Museum (Norway).
