While working late in his Paris darkroom in 1921, the artist inadvertently placed some glass equipment on top of an unexposed sheet of photographic paper. Eventually, a phantom image formed, captivating his attention and spurring a new form he called rayographs. These pieces are among 160 works featured in a new show at The Metropolitan Museum of Art. Man Ray: When Objects Dream will be on view from September 14 through February 1, 2026.
