CFP Forensic Photographer Evidence Preservation & Analysis 5

Question 1

A memory card fails after documenting a major scene. Which prior practice best mitigates this loss?

Accepted Answer

Downloading and verifying images to secure storage as soon as practical, before reusing or transporting cards

Answer

Prompt, verified transfer to secure storage limits the window in which card failure can destroy irreplaceable scene images.

Question 2

Which statement best describes the standard for admissibility of a forensic photograph?

Accepted Answer

It must be a fair and accurate representation of what it purports to depict

Answer

Courts admit photographs when a witness can testify they fairly and accurately represent the scene or object depicted.

Question 3

When photographing fluorescing evidence under an alternate light source, what must be placed on the camera lens?

Accepted Answer

A barrier filter that blocks the excitation light while passing the fluorescence

Answer

A barrier filter (e.g., orange or yellow) blocks the intense excitation wavelength so only the evidence's fluorescence is recorded.

Question 4

An analyst compares a questioned shoe to a photographed shoeprint. What in the photograph makes a reliable one-to-one comparison possible?

Accepted Answer

A calibrated scale in the same plane as the print and a distortion-free, perpendicular capture

Answer

A same-plane scale and perpendicular, distortion-free capture allow the image to be enlarged to natural size for direct comparison.

Question 5

Why should working copies, not originals, be used for image analysis and enhancement?

Accepted Answer

So the original remains pristine as the authoritative reference if results are challenged

Answer

Preserving an untouched original allows any enhancement to be independently verified or repeated from the source.
