Photography is the primary tool for crime scene documentation. Proper crime scene photography is a deliberate and systematic process. Its main purpose is to visually convey all aspects of the scene to someone who wasn’t there. To accomplish this, all crime scene photography consists of three basic types of photographs: overall, mid-range, and close-up.
There’s a certain “Zen” in what ways a crime scene is documented. Thinking behind documentation – “finding mindful awareness of the present” – is as important as methods used. An investigator can have all the current tech available to document a crime, but if they aren’t “in the moment,” their case can fall apart.
