Associate Professor of Photography Tristan Cai opened a solo exhibition, "Imagined Spectres," at the Ionion Center for the Arts and Culture, Kefalonia, Greece. The exhibition showcases the imagined landscapes of primordial earth and the much-hyped sightings of pink snow in alpine environments. Cai presents these wondrous phenomena with large-scale photographs as well as an immersive video installation of the microscopic world of red algae cells obtained from a single drop of melted snow.
