Various photographic methods have been used to document and preserve trace evidence, and both reflective and fluorescent ultraviolet techniques have recently gained acceptance in the courtroom.
Abstract
Ultraviolet photography can be easily accomplished using standard 35-mm camera equipment and films, coupled with an ultraviolet pass band filter. The major difference between visible and ultraviolet light photography is that the image sought in the ultraviolet photograph can only be seen after the film is developed. In documenting evidence of trauma to the skin, the ideal photograph system will allow the investigator to document trace evidence by visualizing the image in real time as it is produced. This is possible with a highly sensitive ultraviolet viewing device. Using the short ultraviolent spectrum and intensified viewer has proven to be useful in wound pattern analysis, while using the long ultraviolet spectrum often allows the investigator to visualize wounds that cannot be seen with the naked eye or via conventional photographic methods. The authors conclude that a reflective ultraviolet imaging system provides forensic investigators with a multifaceted device that can be used to investigate latent prints, wound patterns, trace evidence, body fluids, questioned documents, and crime scenes. 9 references and 7 figures
