Study Notes
Crime Scene Photography
- Forensic photography documents and preserves the original crime scene for future investigation.
- Photographs are used with notes and sketches to form a comprehensive record of forensic documentation.
- Crime scene photos provide important information about the scene, including:
- Layout of the crime scene
- Position of evidence
- Relationship between objects at the scene
Forensic Photography Prerequisites
- The most important requirement for photographing a crime scene is to keep it undisturbed.
- Objects should not be moved unless someone needs immediate medical attention.
- Photography must be completed before any objects are moved.
Admissibility Criteria
- Photographs must accurately reflect the true condition of the scene without alteration.
- Any manipulations to the scene or the photos must be thoroughly documented.
- Photographs must be relevant to the case, proving or disproving arguments.
Digital Photography
- Digital photography is the current standard for crime scene photography.
- A digital camera's light-sensitive microchip captures light from objects or scenes in the crime scene, creating a photograph.
Comprehensive Photography
- Crime scenes should be photographed comprehensively.
- Photos should include the area where the crime occurred as well as surrounding areas.
- Photographs should include an overview of the whole scene and points of entry and exit.
- If applicable, images of the body and all evidence must also be documented.
Overview Photos
- Overview photos are the first images taken to show perspective of the entire scene.
- These photos can be taken from different angles.
- Photos will often start far away and gradually move in to specifics.
Points of Entry/Exit
- Entry and exit points must be clearly photographed to show any marks, indicating force or other pertinent details.
Photographing Evidence
-
Investigators must follow proper techniques for documenting evidence.
-
An item of scale (ruler, quarter, etc.) should be included in the photos for context.
-
Evidence needs to be photographed from three distinct angles and distances.
- Close-up
- Mid-range
- Distance
- A minimum of 9 photos are necessary for each piece of evidence
-
Each piece of evidence is photographed relative to other evidence in the crime scene.
Oblique Lighting
- Oblique lighting is helpful for imaging hard-to-see evidence or detail.
- A light source is positioned at a low angle relative to the evidence.
