CFP Foundational Concepts & Principles 3

Question 1

Why must a forensic photographer avoid using HDR (High Dynamic Range) composite images as primary evidentiary photographs?

Accepted Answer

HDR processing alters pixel data through tone-mapping, potentially misrepresenting the actual scene lighting

Answer

HDR processing merges multiple exposures and applies tone-mapping algorithms that alter original pixel values, raising authenticity concerns in court.

Question 2

What is the purpose of photographing a crime scene using overlapping fields of view?

Accepted Answer

To ensure complete, gap-free coverage so no area of the scene is undocumented

Answer

Overlapping fields of view ensure that every portion of the scene is captured in at least two images, eliminating coverage gaps that could leave evidence undocumented.

Question 3

Which file format is preferred for archiving original forensic photographs to best preserve image data and metadata integrity?

Accepted Answer

RAW (camera native format) or TIFF without compression

Answer

RAW or uncompressed TIFF files preserve all original sensor data and EXIF metadata without lossy compression artifacts, maintaining evidentiary integrity.

Question 4

A witness claims a photograph misrepresents the actual color of evidence. How can a forensic photographer proactively counter such a challenge in court?

Accepted Answer

Include a color calibration reference card (such as a ColorChecker) in at least one photograph of the evidence

Answer

A color calibration card photographed under the same lighting conditions provides an objective, verifiable reference that courts can use to assess color accuracy.

Question 5

In forensic photography, what does 'photo integrity' primarily refer to?

Accepted Answer

The assurance that an image has not been altered from its original captured state

Answer

Photo integrity means the image accurately represents what was captured at the scene and has not been manipulated or altered after the shutter was released.
