What is High-Speed Photography?
High-speed photography is used in many different situations where movement is an issue. For example, it can be used to study how fast an insect flaps its wings. In the case of this question, we are discussing high-speed photography as it is used in medicine.
There are several ways of taking photographs at a high speed. The simplest is to use a flash bulb or a strobe. These light sources create flashes of light that capture a very short period of time. As a result, they are able to take a very rapid series of photographs. A strobe is used in sports photography to freeze the motion of a car. In biology, a strobe is used to photograph the eye movement of a cat or a bird.
There are other types of light source that are much more sophisticated. For example, high-speed cameras that are able to record images in the range of 1000 frames per second. This means that they can film the movement of a single blade of grass in a field or the movement of a butterfly wing. This type of camera is usually attached to a microscope. These can be particularly useful when you want to see how quickly an action can happen.
High-speed cameras are very useful in medical research. They can be used to record the movements of a heart or the beating of a human embryo. By comparing these images, scientists can determine what causes diseases such as high blood pressure.
There are many other uses for high-speed cameras. For example, they are used to film the flow of water in a sewer or the movements of a flame through the air.
High Speed Photography History
High speed photography was discovered by accident by Harold Edgerton. He was experimenting with high speed film and noticed that when a flash of light is flashed onto the film at very high speeds it appears as a streak of light, much like a train coming down a track. This effect was discovered by the world at large, and Harold Edgerton is considered to be the father of high speed photography.
In the beginning, the speed of a film was determined by the number of frames taken on one roll of film. The higher the frame rate, the higher the speed of the film. To achieve even higher frame rates, Harold Edgerton invented the first electronically controlled shutter which allowed the camera to take a burst of pictures without having to stop between each frame. This shutter control is now a standard part of most cameras.
This type of shutter control allows the photographer to choose any combination of frame rate and shutter speed to obtain the best possible picture. With a slow shutter speed the camera can capture only a few frames and a fast shutter speed will allow a whole burst of frames to be taken in a fraction of a second. The higher the frame rate, the faster the film will travel.
The most commonly used frame rate today is 24fps (frames per second) but many other frame rates are in use including 60fps, 100fps and even as high as 240fps. Some still cameras are even capable of taking a burst of 10 or 20 frames a second. A lot of people refer to this method of photography as high speed photography but, technically speaking, the correct term should be high speed photography.
