CFP Forensic Photographer Camera Settings & Exposure Control 3

Question 1

What is the recommended practice for setting the correct shutter speed when using an off-camera flash in forensic photography?

Accepted Answer

Match the shutter speed to the flash sync speed or slower

Answer

Using the flash sync speed or a slower shutter speed ensures the entire sensor is exposed during the flash burst, preventing a black band from appearing across the image.

Question 2

A forensic photographer notices blown highlights (pure white areas) on a light-colored fabric evidence item. What adjustment corrects this?

Accepted Answer

Apply negative exposure compensation

Answer

Negative exposure compensation reduces overall exposure, recovering highlight detail on bright surfaces and preventing loss of texture evidence in pale or white items.

Question 3

What is the primary purpose of using a gray card at a crime scene before photographing evidence?

Accepted Answer

To set a custom white balance for accurate color reproduction

Answer

A gray card reflects a neutral 18% gray, allowing the camera to set a custom white balance and ensuring true-to-life color in evidentiary photographs.

Question 4

When using a DSLR to photograph evidence in a dimly lit room, which combination of settings best balances image quality and exposure?

Accepted Answer

ISO 400, f/8, 1/60s with a tripod

Answer

ISO 400 keeps noise manageable, f/8 provides adequate depth of field, and 1/60s on a tripod allows enough light for a well-exposed, sharp image of stationary evidence.

Question 5

Which technique ensures a forensic photograph of a blood spatter pattern documents the true angle of impact without distortion?

Accepted Answer

Position the camera sensor parallel to the spatter plane

Answer

Aligning the camera sensor parallel to the spatter surface eliminates perspective distortion, allowing accurate measurement and analysis of impact angles in forensic review.
