What is long gray-scale synonymous with?

• A. High contrast and few shades of gray.
• B. Low contrast and many shades of gray.
• C. High dynamic range with bright whites.
• D. Uniform gray without variation.

Answer: (B)

Long gray-scale is about having many tonal steps from black to white. When there are lots of gray levels, transitions are gradual, so the image shows a smooth range of subtle differences rather than sharp jumps. That gives low overall contrast because the light-to-dark difference is spread across many tiny steps, making mid-tones more visible and details easier to distinguish. High contrast with only a few gray levels would be a short gray-scale, producing abrupt changes. High dynamic range aims to preserve details in very bright and very dark areas but isn’t about how long the gray-scale is. A uniform gray has no variation, hence no contrast.
