What does dynamic range describe in digital photography?

• A. The span from darkest shadow to brightest highlight detail a sensor can capture without clipping
• B. The maximum color depth a sensor can record
• C. The rate at which light is captured
• D. The resolution of the image

Answer: (B)

Dynamic range describes the span of brightness values a digital camera sensor can capture in a single exposure—from the darkest shadows to the brightest highlights—without losing detail to clipping. When detail is pushed beyond this range, highlights can blow out to pure white or shadows can fall into pure black, with no information left in those areas. This concept is about how much tonal range the sensor can handle, usually expressed in stops of light.

This is different from color depth, which refers to how many distinct color values the sensor can record per channel, affecting color fidelity and smoothness but not the range of brightness you can capture. It’s also distinct from how fast you’re exposing the image (rate at which light is collected) or the image resolution (how many pixels you have). In practice, a camera with higher dynamic range can better preserve detail in scenes with both bright skies and dark shadows, and photographers often use RAW capture, exposure bracketing, or post-processing to maximize detail across the range.
