Which set lists the three basic aspects of the camera controlled by a crime scene photographer?

• A. Physical Control; Light; Focus and depth of field
• B. Exposure; Metering; White balance
• C. Focus; Shutter speed; ISO
• D. Zoom; Tripod; Color balance

Answer: (A)

The main idea being tested is how a crime scene photographer controls the image to faithfully document evidence. Think of it in three integrated areas: physical control of the camera and setup, lighting and exposure, and focusing with the appropriate depth of field.

Physical control covers how you frame the shot and position yourself and the camera—deciding the angle, distance, and stability, and using supports like a tripod when needed. This determines what evidence is captured and how clearly it will appear in the final image.

Light and exposure involve illuminating the scene so details aren’t lost in shadows or glare and ensuring the camera records it accurately. This includes choosing when and how to light the scene, and setting exposure so that important features remain visible.

Focus and depth of field are about sharpening the key details and controlling what part of the scene is in clear focus. The right focus and an appropriate depth of field ensure critical evidence—like tool marks, fibers, or footprints—are crisp, while less important background elements don’t distract.

Other groupings miss one of these essential facets. For instance, a trio centered on exposure settings emphasizes measurements but not how the scene is physically arranged or how sharp the details will be; a set emphasizing camera settings like shutter speed or ISO focuses on exposure rather than framing and lighting; and a set with equipment terms like zoom or a color balance label highlights tools rather than the broader control of scene, light, and focus.
