The blue LEDs are 470nm, so the BLUE setting should be selected
whenever you are trying to find or photograph bodily fluids such as
urine, semen, saliva, blood , etc. Always use the orange filter when you
are using the blue LEDs! Also, keep in mind that when photograph-
ing a fluorescing object, the angle of incidence is very important. Try
holding the camera at different angles and you will find that some
angles produce a much better result than others. The ambient light
will also affect this. For best results, the CrimeCam Examiner should
be used with the room lights dimmed. Room light off is even better.
A very dim nightlight will be handy. It will take some experimentation
to determine what the ideal lighting conditions are for the scene or
evidence you are photographing.
