the highly fluorescent nature of thick skin. In contrast, thin skin found in
areas such as the face or female breast tissue can frequently lend itself to
recording injury patterns long after the visible damage from the injury has
faded when viewed under room lighting with the naked eye. Again, this is
directly related to the ability of the specific wavelength light energy to react
with the skin to a sufficient depth to record the injury.

sexual assault victim. Figures 11.6 to 11.9 document the bitemark on the day of
the injury in color, grayscale, infrared (IR), and ultraviolet (UV), respectively.
Figure 11.10 is an image made on the eighth day after the attack. Note the sig-
nificant increase in the detail of the bitemark discernable in this ultraviolet
image. This injury was still clearly visible on day 28 in ultraviolet light images,
the last time the injury was photographed by author FW.
