Muybridge's photographic sequence of a race horse galloping, first published in 1878. High-speed photography is the science of taking pictures of very fast phenomena. In 1948, the Society of Motion Picture and Television Engineers (SMPTE) defined high-speed photography as any set of photographs captured by a camera capable of 69 frames per second or greater, and of at least three consecutive ...
Ballistics can be studied using high-speed photography or high-speed cameras. A photo of a Smith & Wesson revolver firing, taken with an ultra high speed air-gap flash. Using this sub-microsecond flash, the bullet can be imaged without motion blur. Ballistics is often broken down into the following four categories: [23]
Common types of photography such as creative and artistic photography give a different purpose than forensic photography. Crime scene photography allows one to capture essential aspects of the crime scene, including its scope, the focal points of the scene, and any physical or material evidence found at or from a result of it. [5]
It is related to, but simpler than, the schlieren and schlieren photography methods that perform a similar function. Shadowgraph is a type of flow visualisation . In principle, a difference in temperature, a different gas, or a shock wave in the transparent air cannot be seen by the human eye or cameras.
With technology like digital photography becoming more common, forensic photography continues to advance and now includes many categories where specialists are required to perform more sophisticated tasks. The use of infrared and ultraviolet light is used for trace evidence photography of fingerprints, tiny blood samples and many other things.
The rapatronic camera (a portmanteau of rapid action electronic) is a high-speed camera capable of recording a still image with an exposure time as brief as 10 nanoseconds. The camera was developed by Harold Edgerton in the 1940s and was first used to photograph the rapidly changing matter in nuclear explosions within milliseconds of detonation ...
For this reason, forensic ballistics examiners may not fire more than five shots from a weapon found at a scene. [3] Known exemplars taken from a seized weapon can be compared to samples recovered from a scene using a comparison microscope as well as newer 3-D imaging technology.
A high-speed camera is a device capable of capturing moving images with exposures of less than 1 / 1 000 second or frame rates in excess of 250 frames per second. [1] It is used for recording fast-moving objects as photographic images onto a storage medium.
