The opening reception for UB art professor John Opera's solo exhibit, "When the Sun is Done," was held Jan. 17 at Rivalry Projects. At the heart of the exhibition are montaged images of diffraction patterns that were captured through custom-built photographic apparatus, shot on film and printed using the gum bichromate process on canvas. Together, the pieces create an environment where subject, light and matter continuously meld and separate. Photos: Douglas Levere
