Photography was only a fledgling art form in the early 1850s when it became a vital source for documenting otherwise unseen corners of the American West. Despite the technical difficulties, the resulting images — sweeping, magisterial views of plains and cliff sides — are unforgettable. The process has found new life in Objects in Perspective, an invigorating collaborative exhibition by Charlotte-based artists Aspen Hochhalter and Natalie Abrams.
