Which parameter describes the system's ability to record a wide range of brightness levels?

• A. Pixel Pitch
• B. Bit Depth
• C. Exposure Latitude
• D. Dynamic Range

Answer: (D)

Dynamic range is the system’s ability to capture a broad span of luminance—from deep shadows to bright highlights—with detail preserved. A wider dynamic range means more brightness levels can be recorded without clipping in highlights or crushing into shadows, which is especially important in scenes with extreme contrast, like a sunset where both the sky and foreground hold detail. Bit depth affects how many tonal steps are available within the captured range, improving the smoothness of tones but not expanding the range itself. Pixel pitch influences spatial resolution and light gathering per pixel, not the span of brightness you can record. Exposure latitude relates to how much over- or under-exposure you can tolerate, which is about practical handling of scenes rather than the sensor’s inherent brightness range. So the parameter that best describes the ability to record a wide range of brightness levels is dynamic range.
