Speed Graphic

Despite the common appellation of Speed Graphic, various Graphic models were produced between 1912 and 1973. The Speed Graphic was available in 2¼ × 3¼ inch, 3¼ × 4¼ inch, 5 × 7 inch and the most common format 4 × 5 inch. Because of the focal plane shutter, the Speed Graphic can also use lenses that do not have shutters (known as barrel lenses). Even faster exposures could be taken if the photographer was shooting film packs of 12 exposures, or later 16 exposures (discontinued in the late 1970s). With film packs one could shoot as fast as one could pull the tab and cock the shutter, and film packs could be loaded in daylight. A roll film adapter that used 120 or 220 film was available for 2.25 × 3.25, 3.25 × 4.25 and 4 × 5 inch cameras that permitted 8 to 20 exposures per roll, depending on the model of the adapter. Photographers had to be conservative and anticipate when the action was about to take place to take the right picture. The cry, "Just one more!" if a shot was missed was common. President Harry Truman introduced the White House photographers as the "Just One More Club." Operation of the focal plane shutter The focal plane shutter consists of a rubberized flexible curtain with slits of varying widths that cross the film plane at speeds determined by the tension setting of the spring mechanism. There are 4 slits with widths of 1/8 in, 3/8 in, 3/4 in, 1 1/2 in and “T” (T = “time” setting, used when lens diaphragm shutter is used to control exposure duration. The focal plane shutter is left completely open until manually released. The opening covers the entire area of the film for the size of the camera.) On Speed Graphic models, there are 6 tension settings, adjusted by a butterfly winding knob that increases the speed that the slit crosses the film plane. On Pacemaker Graphic models, there are only 2 settings (high and low). The combination of the slit width and the spring tension allows for exposure speeds varying from 1/10 to 1/1000 sec. ==Famous users==

A famous Speed Graphic user was New York City press photographer Arthur "Weegee" Fellig, who covered the city in the 1930s and 1940s. Barbara Morgan used a Speed Graphic to photograph Martha Graham's choreography. Recent auctions show Irving Klaw used one in his studio for his iconic pin up & bondage photos of models such as Bettie Page. In the 1950s and 1960s, the iconic photo-journalists of the Washington Post and the former Washington Evening Star shot on Speed Graphics exclusively. Some of the most famous photographs of this era were taken on the device by the twin brothers, Frank P. Hoy (for the Post) and Tom Hoy (for the Star). The 1942-1953 Pulitzer Prizes for photography were taken with Speed Graphic cameras, including AP photographer Joe Rosenthal's image of Marines raising the American flag on Iwo Jima in 1945. to cover John Kerry's presidential campaign. Burnett also used a 4×5 inch Speed Graphic to shoot images at the Winter and Summer Olympics. ==Graflex manufacturing history==

The company name changed several times over the years as it was acquired and later spun off by the Eastman Kodak Company, finally becoming a division of the Singer Corporation and then dissolved in 1973. The award-winning Graflex plant in Pittsford, New York is still standing and is home to Veramark Technologies, Inc., formerly known as the MOSCOM Corporation. ==Graflex model history==

The Speed Graphic was manufactured in a number of sizes, 4×5" being the most common, but also in 2.25×3.25", 3.25×4.25" and 5×7". ==Notes==
