What does dynamic range describe in digital photography?

The range of ISO values The length of shutter speeds The scale of color space The span between darkest and brightest tones that the sensor can record with detail; higher dynamic range preserves detail in shadows and highlights

Correct Answer:

The span between darkest and brightest tones that the sensor can record with detail; higher dynamic range preserves detail in shadows and highlights

Explanation:

Dynamic range describes the span of brightness levels from the darkest to the brightest that a camera sensor can record with detail. If a scene has both bright highlights and deep shadows, a sensor with limited dynamic range may blow out the highlights or leave the shadows looking flat and noisy. A higher dynamic range means more tonal information across those stops, so you can preserve detail in both ends of the spectrum or recover detail in post. This is why the correct choice talks about the range of tones the sensor can capture and how preserving detail in shadows and highlights is possible with greater dynamic range. It’s not about ISO range, shutter length, or color space.
