CFP Forensic Photographer Evidence Preservation & Analysis 4

Question 1

Ultraviolet (UV) and infrared (IR) photography are used in evidence analysis primarily to do what?

Accepted Answer

Visualize details invisible in normal light, such as bruising, altered documents, or gunshot residue

Answer

Alternate light and IR/UV imaging reveal absorption and reflection differences that expose evidence the eye cannot see under white light.

Question 2

When photographing luminol or other chemiluminescent reactions, which approach is required?

Accepted Answer

Long exposure on a tripod in darkness, with a reference exposure of the same area under normal light

Answer

The faint glow needs a stabilized long exposure in darkness, paired with a normal-light image so the reaction's location can be oriented in the scene.

Question 3

What metadata embedded in a digital image file is most useful for authentication?

Accepted Answer

Capture date, time, camera settings, and device identifiers recorded in EXIF data

Answer

EXIF metadata corroborates when, how, and with what equipment an image was made, supporting its authenticity.

Question 4

A defense expert claims a scene photograph misrepresents distances. Which capture practice best defends against this challenge?

Accepted Answer

Having used a normal focal length lens and documented camera positions rather than extreme wide-angle or telephoto views

Answer

Normal focal lengths approximate human perspective, and documented camera positions let spatial relationships be verified.

Question 5

How should original digital evidence images be archived for long-term preservation?

Accepted Answer

On secure, redundant, write-protected storage with restricted, logged access

Answer

Long-term integrity requires redundant, access-controlled, write-once storage so originals cannot be altered or lost.
