CFP Forensic Photographer Camera Settings & Exposure Control 2 — Questions and Answers
Question 1: What white balance setting should a forensic photographer choose when photographing under standard fluorescent lighting?
- Daylight (5500K)
- Tungsten (3200K)
- Fluorescent (4200K) (Correct answer)
- Shade (7000K)
Correct answer: Fluorescent (4200K)
Selecting the fluorescent white balance preset compensates for the green color cast produced by standard fluorescent lighting, rendering colors accurately in evidentiary photos.
Question 2: Which focus mode is best suited for photographing stationary evidence such as a shell casing at a crime scene?
- Continuous autofocus (AI Servo/AF-C)
- Single autofocus (One-Shot/AF-S) (Correct answer)
- Manual focus only
- Face-detection autofocus
Correct answer: Single autofocus (One-Shot/AF-S)
Single autofocus locks focus on a stationary subject and holds it, ensuring sharp detail on non-moving evidence items.
Question 3: A forensic photographer needs to capture a ruler alongside a bullet for scale. Which lens focal length minimizes perspective distortion?
- 14mm wide-angle
- 24mm wide-angle
- 50mm standard
- 100mm macro (Correct answer)
Correct answer: 100mm macro
A macro lens at around 100mm provides a flat, undistorted perspective that accurately represents the size relationship between the evidence and the scale ruler.
Question 4: What does the histogram in a camera viewfinder indicate to a forensic photographer?
- The geographic coordinates of the image
- The tonal distribution of light and dark values in the frame (Correct answer)
- The number of images remaining on the memory card
- The autofocus lock confirmation
Correct answer: The tonal distribution of light and dark values in the frame
The histogram shows the distribution of tonal values from black to white, helping the forensic photographer verify proper exposure without losing shadow or highlight detail.
Question 5: When should a forensic photographer use exposure bracketing at a crime scene?
- Only for portrait shots of witnesses
- When lighting conditions are uncertain or mixed, to ensure at least one correctly exposed image (Correct answer)
- Only when using film cameras
- Exclusively for aerial photography
Correct answer: When lighting conditions are uncertain or mixed, to ensure at least one correctly exposed image
Exposure bracketing captures multiple frames at different exposures, guaranteeing a properly exposed image of critical evidence when lighting is challenging or unpredictable.
Question 6: Which image stabilization consideration is most important when photographing evidence at slow shutter speeds without a tripod?
- Disable image stabilization for sharper results
- Enable image stabilization to reduce camera shake blur (Correct answer)
- Use burst mode to compensate for shake
- Increase ISO to maximum to avoid shake
Correct answer: Enable image stabilization to reduce camera shake blur
Enabling in-lens or in-body image stabilization counteracts hand tremors at slow shutter speeds, reducing motion blur and preserving evidentiary detail.
