Daguerreotype? Gelatin silver print? C-print? Cyanotype? Digital print? Since the invention of photography in 1839, the physical process of making a photograph has evolved time and time again, and the material and philosophical boundaries of photography continue to expand. Explore prints from MoMA's collection and reflect upon what constitutes a photograph in the 21st century.

Gallery Sessions, impromptu interactions facilitated by Museum educators that explore the creative process, art history, and the experience of art, take place daily in select galleries. Groups meet in the galleries noted on the schedule. Gallery Sessions are free with Museum admission. No registration is required.

FM headsets for sound amplification are available for all talks.
