High-speed photography is an engineering tool, much as is an oscilloscope or a computer. It is a photographic technique that enables us to visualize and analyze motion. Especially motions that are too fast for the human eye or conventional cameras to perceive. It also helps with motion control.
The science behind the high-speed photography
The art of high-speed photography records these kinds of fast-moving objects, documenting things that are normally invisible to the human eye. Scientists use high-speed photographs to study physical movement, measuring phenomena like surface tension and gravitational effects. The military takes high-speed pictures to look at the accuracy of missiles and rockets, and it's even possible to record what's happening at the very core of nuclear explosions. Sports photographers also use high-speed photography to shoot fast-moving sporting events like bike racing and horse racing. High-speed photography also has its artistic merits, as art galleries and magazines often display stunning high-speed photographs.
In common usage, high-speed photography may refer to either or both of the following meanings. The first is that the photograph itself may be taken in a way as to appear to freeze the motion, especially to reduce motion blur. The second is that a series of photographs may be taken at a high sampling frequency or frame rate. The first requires a sensor with good sensitivity and either a very good shuttering system or a very fast strobe light. The second requires some means of capturing successive frames, either with a mechanical device or by moving data off electronic sensors very quickly.
The most popular high-speed cameras are Bolt and Phantom models
