Although the brightness of these images has been adjusted to display similar average gray values, notice the noisy appearance of the underexposed periapical radiograph (Fig. 4-16, A, 0.032 second) compared with the properly exposed radiograph (Fig. 4-16, B, 0.32 second).
likely from underexposed
exposure of a PSP plate to ambient light will cause?
