It is commonplace to think of photographs as being just a simple document of times that we have enjoyed in the past, but the fact of the matter is that photography is a versatile medium and has various uses for different people. While there is no better way to document a holiday or a wedding, photography has played a major part in many other ways over the years.
In the case of crime fighting, any sealed-off crime scene will soon be attended by photographers who take pictures of potentially important scenes. They will look to capture pieces of evidence, show the crime scene as it looks to someone who was there and look to preserve the scene for the defence, prosecution and jury to have some idea of what they are dealing with.
In sport, the importance of photography goes well beyond the illustration of game day reports. For example, athletics places a great importance upon the use of photographic technology to help separate two athletes that appear to have finished dead level. A photo finish can separate athletes to the nearest thousandth of a second, and even closer.
Then, of course, there is the use of photography in medicine. There are a few different ways that this can be applied. Pinhole cameras can be used to get an internal picture of a patient to find the cause of an illness or to guide surgery, as well as X-ray photographs which are often essential for diagnosing bone fractures and other injuries.
