Study Notes
Objectives of Crime Scene Photography
- Complete and accurate photographic documentation of crime scenes is crucial for any criminal investigation.
- Images captured through digital photography provide a valuable link between evidence and the context in which it was found.
- Downstream users of crime scene images include Forensic Pathologists, Forensic Units, and Courts of Law.
Composure of Images
- Crime scene photographers must properly "compose" their images, considering the mechanical operation of the camera.
- Every evidence item needs to be oriented within the crime scene, shown in relation to other pieces of evidence.
- Evidence items must be properly photographed in close-up detail.
- Simply recording one or two images prior to an item's recovery is not sufficient for achieving a full understanding of the evidence.
Technical Photographs
- Technical photographs are images that show as much detail or information about the view or object pictured as possible.
- The best technical photographs have four key characteristics: correct exposure, maximum depth of field, freedom from distortion, and sharp focus.
- Correct exposure is necessary for capturing detail in all parts of a scene, including highlight areas and shadows.
- Underexposure results in loss of detail in shadows, while overexposure results in loss of detail in highlight areas.
- Lighting is crucial for capturing forensic evidence, and accurate capture of light is essential for technical photographs.
