Alternate Light Source Workshop

This course is hosted by the Gig Harbor Police Department.

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.
