Made possible by the invention of laser technology in the 1960s, holograms produce the illusion of three-dimensional objects floating in space. Many artists have experimented with holography: Louise Bourgeois, Ed Ruscha, and others were invited by the C Project to explore the creative potential of the medium in the late 1990s, and Deana Lawson turned to holography to expand her photographic practice around 2020. The master technician in both instances was Matthew Schreiber, an artist in his own right, whose work is also featured.
