Summary:Image processing opens up new areas of open-ended learning in the classroom. Unlike photographs, images are numerical entities. Specific numbers represent specific colours; by changing the numbers, subtle differences on the natural colour original can stand out in breathtaking contrast in the processed false colour image. The technique may be used for a diverse range of tasks, as shown, from determining the cratering sequence on Venus to delineating the worked areas on an Aboriginal stone axehead. [Author abstract]
