Abstract

With the advent of relatively inexpensive image-handling computer programmes, digital image enhancement is more readily available to archaeologists. This paper describes the principles behind image enhancement and its application to rock-art in particular. Its use at a site in Torres Strait shows how it can be used successfully to reveal faded rock paintings.
