Profoto's Pro-B4: The Fastest Battery Generator in the World. ~ 1/25,000 of a Second!

Award-winning photographer Marcel Lämmerhirt was the first photographer to ever lay his hands on the Pro-B4. Marcel, who loves to shoot fast and extreme sports, was especially impressed by its speed and action-freezing capability. He decided to use these unique features to take a sequence shot of the world champion in wakeboarding, Dominik Gührs.

Pro-B4 1000 Air battery generator, featuring flash durations down to 1/25,000 of a second. At lower power settings the Profoto Pro-B4 1000 Air is capable of firing up to 30 flashes per second, while the maximum recycle time after a full-power discharge is less than a second.

Photographer Profile ~ Harold "Doc" Edgerton.

Born in Fremont, Nebraska, Harold "Doc" Edgerton (1903-1990) began his graduate studies at MIT in 1926. He became a professor of electrical engineering at MIT in 1934. In 1966, he was named Institute Professor, MIT's highest honor.

With his development of the electronic stroboscope, Edgerton set into motion a lifelong course of innovation centered on a single idea – making the invisible visible. An inveterate problem-solver, Edgerton succeeded in photographing phenomena that were too bright or too dim or moved too quickly or too slowly to be captured with traditional photography.

In the early days of his career, Edgerton's subjects were motors, running water and drops splashing, bats and hummingbirds in flight, golfers and footballers in motion, his children at play. By the time of his death at the age of 86, Edgerton had developed dozens of practical applications for stroboscopy, some that would influence the course of history.

The strides that Edgerton made in night aerial photography during World War II were instrumental to the success of the Normandy invasion and, for his contribution to the war effort, Doc was awarded the Medal of Freedom. During the Cold War, Edgerton and his partners at EG&G (Edgerton, Germeshausen, and Grier) made it possible to document nuclear explosions, an advance of incalculable scientific significance. In the last three decades of his life, Edgerton concentrated on sonar and underwater photography, illuminating the depths of the ocean for undersea explorers such as Jacques Cousteau, who dubbed his good friend "Papa Flash."

Doc's genius for revealing slices of time to the naked eye also engaged the public imagination. In part, this had to do with his astute choice of subject matter: Mickey Rooney and Judy Garland, the acrobats of the Moscow Circus, British tennis star Gussie Moran. But Doc's most famous study – and possibly his favorite – the milk-drop coronet, transcended its simple subject. The image, formed by the splash of a drop of milk, not only introduced the poetry of physics into popular culture, but forever altered the visual vocabulary of photography and science.

National Geographic used many of Edgerton's photographs as illustrations for its articles, and published a number of articles by Edgerton himself. Edgerton's photographs are exhibited in museums, including the Museum of Modern Art in New York City and the Victoria and Albert Museum in London.

Although many consider Edgerton's work art, he said, “Don’t make me out to be an artist. I am an engineer. I am after the facts. Only the facts.”

Edgerton's notes show a measurement of 166 feet per second during Bobby's swing, which comes out to around 112 mph! Super fast for this era's heavier equipment!
