A radiograph with few shades of gray exhibits what type of contrast?

Explanation:
The question tests how contrast relates to the grayscale range on a radiograph. When an image shows only a few gray shades, the tones are limited, so differences between dense structures (like bone) and softer tissues appear as stark black and white with few intermediate tones. This limited grayscale creates a high-contrast image, where edges and boundaries stand out clearly. If there were many gray tones, you’d have low (long-scale) contrast, with more gradual shading. If the image were uniform without variation, that would be no contrast at all.
