Graflex Revolving Back (RB) Graflex Series B

The Revolving Back (RB) Graflex Series B represents a significant evolution in professional large format photography during the 20th century. Produced by Graflex Inc. from 1923 to 1951, it built upon the company's reputation for robust cameras favored by press and portrait photographers. Its defining feature was the innovative revolving back mechanism, a sophisticated metal frame that allowed photographers to effortlessly switch between vertical (portrait) and horizontal (landscape) orientations without removing the ground glass or the film holder. This proved invaluable for fast-paced assignments, particularly in photojournalism where capturing decisive moments quickly was paramount. Constructed predominantly from cast aluminum and brass, the Series B maintained the classic, sturdy "Speed Graphic" silhouette known for its reliability and distinctive rangefinder/focusing hood assembly. It was a workhorse camera, widely used by press photographers throughout World War II and beyond, documented in iconic images of the era.

While sharing the core design lineage with earlier Graflex SLRs and the ubiquitous Speed Graphic models, the RB Series B differentiated itself primarily through its revolving back functionality. This innovation streamlined the workflow for professionals needing compositional flexibility without sacrificing the 4x5 inch negative's inherent quality and detail. Its focal plane shutter provided adjustable speeds and synchronization capabilities, further expanding its versatility for both studio and field use. Although not as famous as the Leica M3 or Nikon F in the realm of small format revolution, the RB Series B holds a crucial place as a tool that defined professional practice in the large format press and portrait world for nearly three decades. Its association with legendary photographers who captured history through its lens underscores its enduring legacy as a practical and highly capable instrument of its time.
