The term used for the usable exposure range of film or digital sensors is dynamic range. Dynamic range refers to the difference between the maximum and minimum light intensities that a sensor or film can capture, allowing it to produce details in both the highlights and shadows. A sensor with a broader dynamic range can record more subtle nuances in light and detail, which is crucial for high-contrast scenes where both bright and dark areas need to be represented accurately.

This concept is fundamental in photography because it influences how well a captured image can retain detail across various lighting conditions. The greater the dynamic range, the more detail a photographer can recover in post-processing, making images look more natural and appealing.

In contrast, exposure latitude refers to the range of exposure settings that will produce usable results for a given film or sensor and is related but not identical to dynamic range. Color gamut pertains to the range of colors that a device can capture or reproduce, which is a different aspect of image quality. Image depth typically relates to the bit depth of an image file, which affects color information rather than exposure range.
