Applying a high-contrast look-up table (LUT) to a chest radiograph would produce which grayscale result?

Explanation:
A high-contrast LUT increases the slope of the display transfer function, pushing mid-range pixel values toward the extremes. This magnifies differences between bright and dark areas while compressing the many midtones, so most pixels end up near black or near white. On a chest radiograph, that means only a few gray levels remain between the darkest and lightest parts. The image would appear with strong edges and fewer intermediate tones, rather than a wide range of grays.
