Which kVp setting produces long-scale image contrast?

a. 65 kVp
b. 75 kVp
c. 85 kVp
d. 95 kVp

d. Long-scale contrast describes a radiograph in which the density differences between adjacent areas are small. The contrast is low and very gradual because there are many shades of gray. Such radiographs result when high (80–100) kVp is applied.
