Study Notes
Crime Scene Photography
- Forensic photography documents and preserves the crime scene for future investigation.
- Photos are crucial for documentation alongside notes and sketches.
- Crime scene photos are essential for showing:
- Layout of the crime scene
- Position of evidence
- Relationship of objects at the scene
- The crime scene must remain unaltered before photography, except for cases where medical attention is needed.
- Admissible crime scene photos must accurately reflect the scene's true condition without alterations.
- Manipulations must be documented.
- Photos must be relevant to the case—supporting or undermining facts.
Digital Photography
- Digital photography is the preferred method for crime scenes.
- A digital photo is created when a light-sensitive microchip in a digital camera is exposed to light from the object or scene.
Crime Scene Photography Procedures
- Photograph the crime scene as completely as possible.
- Photos should include:
- Area where the crime occurred
- Adjacent areas
- Overview shots
- Entry and exit points
- Body (if relevant)
- Evidence
Overview Photos
- Initial photos are overview photos, encompassing the entire scene and surrounding area.
- Photos may use a natural perspective or, in some cases, aerial views.
- Photos should start at a distance, gradually zooming in to focus on a specific area of the crime.
- Images should be taken from various angles at the edges of the scene.
Points of Entry/Exit
- Points of entry and exit in a crime scene must be photographed to show any signs of force.
Photographing Evidence
- Use proper technique for evidence photography—including an item of scale (e.g., ruler, quarter).
- Each piece of evidence must be photographed from three different angles (minimum) at three different distances (close, middle, and long-range). This translates to nine photos per piece of evidence.
- The evidence's position and location relative to the entire scene should be documented.
Oblique Lighting
- Oblique lighting can make hard-to-see evidence visible.
- It uses a light source positioned at a low angle to create shadows on evidence.
- It is commonly used for impressions, tool marks, and some types of fingerprints.
Additional Information
- The images or photos in the presentation are examples of overview shots and photographed evidence in crime scenes.
