11.4 Properties of Injured Skin: Inflammation and Repair
In forensic photography it is equally important to understand the physiologi-
cal changes that occur in living tissue when skin is injured. These changes
from normal to injured to healing states allow discriminatory recording of
the contusions illuminated by light sources of various wavelengths.
Since the healing process is long term and ongoing, it is sometimes
possible to photograph an injury after that tissue appears to have healed to
the naked eye. Similarly, photographing the same injuries over time using
both visible and nonvisible light techniques can yield different appear-
ances of those injuries, which can sometimes add to their evidentiary value
(Figures 11.2 to 11.10).
