A key challenge in rock art research has involved developing methods to assist in recovering and documenting deteriorated and superimposed pigment art. The " digital revolution " has played a crucial role in this endeavor as it has brought many new and innovative ways of seeing and recording rock art. In this chapter, we examine the methods and results generated from using computer enhancement techniques. Given the potential of these techniques to shed light on aspects of assemblages that may have been missed using conventional recording strategies, we argue that these techniques must now form an integral component of recording methodologies.
