"Depth of Field" refers to the range of distances in a scene that appears acceptably sharp in an image. It is a critical concept in photography and imaging as it affects how much of the scene will be in focus, influencing the artistic and narrative elements of a photograph. A shallow depth of field isolates the subject against a blurred background, which is often used in portrait photography to draw attention to the subject. In contrast, a deep depth of field keeps more of the scene in focus, which is commonly utilized in landscape photography to showcase more detail throughout the image.

The other options do not accurately represent what depth of field entails. Brightness deals with the exposure and lighting of an image, resolution pertains to the level of detail present in the image, and color saturation refers to the vividness or intensity of colors in the photograph. Each of these aspects can interact with depth of field but does not define it. Thus, "Depth of Field" specifically denotes the range of distances in focus within an image.
