What is defined as the density difference between light and dark areas on a processed radiograph, and can be read from the characteristic curve?

Explanation:
Contrast is the density difference between light and dark areas on a processed radiograph. It reflects how well structures with different attenuation are distinguished. On the characteristic curve, the slope in the useful exposure range represents this contrast: a steeper slope means higher contrast (small changes in exposure yield large changes in density), while a flatter slope means lower contrast. Density itself is the overall darkness at a point, brightness is the perception on display, and sharpness relates to edge definition, not the difference in density between areas.
