Which camera sensor characteristic most directly determines the ability to capture fine detail in a fingerprint examination-quality photograph?
Answer: Sensor resolution (pixel count relative to subject area)
Examination-quality images require sufficient pixel resolution across the subject, typically 1000 ppi for fingerprints.
A forensic photographer needs to document a shoe impression in soil. Which lighting tool and technique is most appropriate?
Answer: Off-camera flash held at a low oblique angle
Low-angle oblique lighting from an off-camera flash creates shadows that reveal three-dimensional impression detail.
What is the primary advantage of capturing crime scene images in RAW format rather than JPEG?
Answer: RAW retains unprocessed sensor data, allowing lossless adjustment and stronger authentication
RAW preserves all original sensor data without lossy compression, supporting both image quality and evidentiary integrity.
Which filter is typically paired with an alternate light source (ALS) at 450 nm to visualize fluorescing biological stains?
Answer: Orange or yellow barrier filter
An orange or yellow barrier filter blocks the reflected blue excitation light so only the fluorescence is recorded.
When photographing evidence at a 1:1 reproduction ratio, which piece of equipment is essential?
Answer: A macro lens capable of life-size magnification
True macro lenses achieve 1:1 magnification, rendering the subject at life size on the sensor.
A tripod-mounted camera with a remote shutter release is most critical in which forensic scenario?
Answer: Long-exposure painting-with-light photography of a nighttime outdoor scene
Long exposures require complete camera stability, which the tripod and remote release provide by eliminating touch-induced vibration.
What is the function of a color checker or gray card included in evidence photographs?
Answer: It provides a reference for accurate white balance and color reproduction
A calibrated gray card or color chart lets examiners correct color and exposure to true values later.
