When shooting in RAW format at a crime scene, which action during post-processing would be considered forensically unacceptable?
Answer: Removing or cloning out visible evidence items
Removing or cloning out any element from a forensic photograph constitutes alteration of evidence and is legally and ethically impermissible.
Focus stacking is most useful in forensic photography when:
Answer: Capturing a small three-dimensional piece of evidence where total sharpness is required
Focus stacking combines multiple images taken at different focus distances to create a single fully-sharp image of a small 3D object that exceeds a single lens's depth of field.
A forensic photographer documents a suspected accelerant pour pattern on a fire-damaged floor. Which photographic approach would best capture the pattern boundaries?
Answer: Color photography with a tripod-mounted overhead shot and measurement scale
An overhead, tripod-mounted shot with a measurement scale provides an undistorted, accurately scaled view of the pour pattern's shape and dimensions.
The term 'chain of custody' in forensic photography refers to:
Answer: The documented chronological record of who handled photographic evidence from capture to court
Chain of custody documents every person who handled the photographic evidence, ensuring its integrity and admissibility from the moment of capture through court presentation.
When documenting a crime scene in low-light conditions, a forensic photographer should avoid using high ISO settings primarily because:
Answer: Excessive digital noise can obscure fine details critical to forensic examination
High ISO generates digital noise that can mask fine detail such as fingerprint ridges, fiber evidence, or subtle wound characteristics essential to forensic analysis.
In forensic photography, using a 1:1 macro reproduction ratio means:
Answer: The image on the sensor is the same size as the actual subject
A 1:1 reproduction ratio means the subject is rendered at life size on the sensor, which is essential for accurate scale documentation of small evidence items.
A photographer discovers that a key piece of evidence was accidentally photographed without an ABFO scale marker. The correct response is to:
Answer: Place the scale next to the evidence and rephotograph it before the scene is cleared
If the scene is still active and evidence is undisturbed, the photographer should place an ABFO scale and rephotograph immediately to preserve evidentiary value.
