FRSC 3010 LECTURE 2 EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
scene photos
• General photos taken of the scene prior to processing
• Shows everything as found
• Not a defined process
• Painting a picture
• As found by the police forensic unit upon arrival
exhibit photos
• A specific set of photos of an exhibit/object/piece of evidence
• Follows a defined process
• Consists of a series of photos (typically 4)
• Area where exhibit/evidence should be in scene photos (front stairs)
crime scene photography
• Do not need to be a professional photographer
• Need to be competent with a camera and its accessories
• Should have formal training (for court purposes)
• Understand the criteria for photographs being admissible in court
camera technique
• Correct technique when holding a digital camera
• Right hand holds camera body by right side/grip
• Left hand holds/supports barrel of the lens from underneath
,Crime scene photos
• The scene is photographed from many different directions and angles to show the
layout of the scene,capture the position of the evidence to be collected and show spatial
relationships between items
• Photographs can document the perspective of any known witnesses as well as any
potential witnesses
• These photographs are important as they may be used for further analysis by experts
and investigators
• Ultimately they may end up being shown in court or inquests where they will be viewed
by lawyers, jurors,witnesses and the public
• Crime scene photographs record the area in which the crime took place and all other
areas of importance in relation to that scene (secondary scenes)
• Photos should be taken before the scene is processed (altered)
• Each crime scene should be photographed as completely as possible in a logical
succession from general to specific.
• The sequence will show the overall scene first, then work down to individual pieces of
evidence that can easily be related back to the larger scene
overall photos
need to be taken of any crime scene before any processing can begin
• This can be a street, a field, a house, a hallway or a room
• These overall photos give context to the evidence that may be found within the crime
scene
, • Always take a few more photos than may be necessary
• Don't get caught up in how many photos have been taken
what are the four photos required for a specific item (evidence/exhibit)
1) an overall photograph
2) a mid range photograph
3) a close-up photograph
4) a close-up photograph with a scale
Digital Single Lens Reflex (DSLR) Camera
is the type typically used for crime scene photography. What you see through the
viewfinder (or LCD monitor) is how the photo will turn out
digital photograph
• is made when a light sensitive microchip (sensor) captures light on each of millions of
tiny picture elements, called pixels
• The light is recorded on each pixel as a specific electric charge which is read by the
camera as image information which is stored as a file on a memory card
Charged Coupled Device (CCD)
• Digital equivalent of film
• CCD contains millions of silicon photo sensors
• Each photo sensor is a pixel or picture element
• Image passes through lens and is focused onto a CCD (film plane)
• Exposure (amount of light) is controlled by shutter speed/aperture*
