Crime Scene Cameras
Conventional silver-based film is still the recommended technology for evidentiary photography or for field applications. These cameras offer the highest resolution possibilities as well as the highest dynamic range. They have the best color range and are the most flexible of the currently available camera technology options. Silver-based film is the most durable storage medium as well, and is more readily available than video or digital storage media ("Guidelines). Resolution quality, or the sharpness of detail, is one of the most significant advantages of silver-based film. The extremely small sized silver crystals for this type of film allow silver-based film cameras to have a much higher resolution than digital cameras. 35mm camera negatives have an approximate resolution of 5500 x 3600 pixels, while digital cameras typically only have a resolution of 640 x 480 pixels. That equates to only 1.6 percent of the information that is captured with a silver-based film camera being captured with a digital camera ("Guidelines"). There are disadvantages to using this sort of camera, however. First is the need for a separate processing and printing facilities. In addition, there is a relatively long processing time involved
Digital cameras offer some distinct advantages over other types of cameras. The foremost benefit they offer the user is the ability to view the image instantly and verify that image is exactly what was wanted. In addition, the image can be transmitted or shared with very few intermediate steps. Onsite image management as well as printing are added advantages, as well as more environmentally friendly media than film ("Guidelines"). Hybrid imaging systems combine silver-based film technology with digital technology. The advantages of this type of system is that there is less time to be spent in the darkroom and the camera maintains the high-quality film images. With this high quality, there is still the flexibility that comes with digital image processing. Just like digital cameras, images can easily be transferred electronically and can be analyzed electronically as well. This system also simplifies case-file management and can use a variety of output devices ("Guidelines"). Advantages and Disadvantages of Video Cameras: There are disadvantages to this system, however. There is still a need for separate processing and printing facilities for the silver-based film, which includes the lengthy processing time and the environmentally hazardous byproducts. Just like a regular silver-based film camera, the preprocessed film is fragile and can be damaged by temperature, humidity and x-rays. And, it requires increased technical support, unlike a regular silver-based film camera ("Guidelines"). for silver-based film. Processing the film also creates environmentally hazardous byproducts, in addition the film prior to processing is sensitive to temperature and humidity changes, as well as x-rays. T
