Which of the following features of digital imaging software currently available provides the best aid to interpreting digital images?

a. Density/contrast manipulation
b. Colorization
c. Embossing
d. Reversing the gray scale

a. Accurate diagnosis of radiographs depends on the practitioner's ability to distinguish changes in the gray scale. Therefore, ability to improve the density and contrast of the image will aid in interpretation. Other features of specialized software promoted by manufacturers such as colorization, embossing, and reversing the gray scale may be only visual gimmicks because these features currently do not have the power to take the place of the dental practitioner.
