Which statement best characterizes an image with long gray-scale and many shades of gray?

Explanation:
A long gray-scale with many shades of gray indicates low contrast. When an image contains a wide range of gray tones, the differences between neighboring pixel values are small, so transitions appear gradual and edges are less distinct. That’s the hallmark of a low-contrast image: a smooth, subtle variation in brightness rather than sharp black-and-white separation. In contrast, a high-contrast image shows stark differences with few gray tones—mostly black and white with little in between. No contrast would mean a uniform image with essentially no variation, and medium contrast would fall somewhere in between, with a moderate number of gray tones.
