Custom Alternate Light Source Workshop
Alternate Light Sources (ALS) are tools that can permit investigators to locate, process, and photograph otherwise invisible evidence. Understanding how these devices work is helpful in applying them correctly at the crime scene or in the laboratory. This course begins with a discussion of the properties of light and luminescence and culminates in the use of the ALS to visualize and photograph items of evidence. A review of basic photography and the use more advanced photographic techniques to optimize image quality will be included.
Special emphasis in this custom course will be placed on the documentation of bodily injuries through the use of the ALS. Because different wavelengths of light interact with human skin differently, the ALS is ideally used to document bruising that occurs near the surface of the victim's skin. Sometimes certain wavelengths make bruises visible that are not otherwise clearly visible under normal lighting conditions.
Also demonstrated in this course will be reflective infrared photography. Through the use of specially modified cameras, forensic photographers can capture deep tissue bruising visible only in the infrared waveband of the spectrum of light. A variety of different types of Alternate Light Sources will be on-hand for use by the students. The ability to use different types of units will permit students to judge which type of light source best suits their needs and will assist leadworkers in establishing their agency’s protocols, procedures, and work-flow.
This course will heavily emphasize instruction using handson techniques. Due to the amount of hands-on training in this course, enrollment is limited to 20 students. Students are encouraged to bring the digital camera used in their work. This is an advanced course; students are expected to have an understanding of basic photography and camera operation prior to attendance.
