Ray K. Metzker (September 10, 1931 – October 9, 2014) was an American photographer known chiefly for his bold, experimental B&W cityscapes and for his large "composites", assemblages of printed film strips and single frames. His work is held in various major public collections and is the subject of eight monographs. He received awards from the John Simon Guggenheim Memorial Foundation, National Endowment for the Arts and Royal Photographic Society.
