Wynn Bullock typed out an Albert Einstein quote he appreciated on an index card he used as a bookmark that could have served as a career leitmotif for the California photographer. “The most beautiful thing we can experience is the mysterious,” it read, in part. “It is the source of all true art and science.”

The subject of a major retrospective opening Saturday at the High Museum of Art, Bullock was an artist with a scientist’s sensibility, inspired by physics and philosophy among other intellectual pursuits, using his camera to explore the seen and unseen world around him.
