CFP Forensic Photographer Crime Scene Imaging & Documentation 2 — Questions and Answers
Question 1: When photographing a homicide scene, which sequence correctly represents the standard photographic documentation order?
- Close-up, mid-range, overall
- Overall, mid-range, close-up (Correct answer)
- Mid-range, overall, close-up
- Close-up, overall, mid-range
Correct answer: Overall, mid-range, close-up
Crime scene photography follows overall (establishing), mid-range (relationship), then close-up (detail) progression to build context before isolating evidence.
Question 2: A forensic photographer arrives at an outdoor shooting scene at dusk. What is the primary concern when using flash photography in low-light conditions?
- Flash will overexpose background elements
- Flash may create harsh shadows that obscure bullet wound depth (Correct answer)
- Flash batteries drain faster in cold temperatures
- Flash will alter the color of blood evidence
Correct answer: Flash may create harsh shadows that obscure bullet wound depth
Direct on-camera flash at close range creates harsh shadows that can distort the apparent depth and shape of wounds or impression evidence.
Question 3: Which camera setting is most critical to maintain consistency when shooting comparison photographs of tire track evidence at a crime scene?
- White balance
- ISO sensitivity
- Camera-to-subject angle and distance (Correct answer)
- Shutter speed priority mode
Correct answer: Camera-to-subject angle and distance
Maintaining a consistent 90-degree angle directly above the evidence at a fixed distance ensures scale and proportion are not distorted in comparison images.
Question 4: What does the term 'photographic documentation log' include that is NOT captured in the image metadata?
- Shutter speed settings
- GPS coordinates of the camera
- Chain of custody notes for the memory card
- Names of officers present during photography (Correct answer)
Correct answer: Names of officers present during photography
A documentation log records personnel present, scene conditions, and chain-of-custody information that EXIF metadata cannot capture.
Question 5: A forensic photographer must document latent fingerprints developed with fluorescent powder. Which imaging technique produces the best result?
- Normal white-light photography with a macro lens
- UV or alternate light source with a barrier filter and long exposure (Correct answer)
- Infrared photography at 850nm
- HDR photography with tone mapping
Correct answer: UV or alternate light source with a barrier filter and long exposure
Fluorescent-powder-developed prints must be photographed using the matching excitation light and a barrier filter to capture the fluorescence emission while blocking the excitation wavelength.
Question 6: When photographing a vehicle involved in a hit-and-run, which photographic series is essential beyond standard overall and close-up shots?
- 360-degree walk-around series with consistent distance (Correct answer)
- Aerial drone overview of the entire parking lot
- Interior dashboard photographs only
- Undercarriage photographs using wide-angle lens
Correct answer: 360-degree walk-around series with consistent distance
A 360-degree walk-around series at consistent distance documents all vehicle surfaces for contact damage, paint transfer, and biological evidence in a court-defensible sequence.
Question 7: In digital forensic photography, what is the purpose of capturing a 'gray card' or color checker in the first frame of an evidence sequence?
- To calibrate GPS location data in EXIF
- To provide a reference for accurate white balance and color correction in post-processing (Correct answer)
- To document the camera model used
- To establish the time the photograph was taken
Correct answer: To provide a reference for accurate white balance and color correction in post-processing
A calibrated gray card or color checker provides a known reference point that allows accurate white balance and color correction during post-processing without altering evidentiary image data.
