Relief modelling is a very peculiar task that requires the creation of three-dimensional forms onto two dimensional surfaces to depict depth and volume in a composition. Preliminary research revealed that students in the Sculpture section in the Department of Painting and Sculpture in the Kwame Nkrumah University of Science and Technology faced the challenge of producing relief sculptural pieces to give them the three dimensionality that suggests volume and depth. This project work that utilized studio-based research approach rooted in the constructivism theory was aimed at experimenting on how to overcome the flaws in relief modelling using the chiaroscuro technique. Twelve (12) student-sculptors participated in this project using the stratified sampling technique. They were taken through practical sessions in modelling compositions of geometric forms, still-life, and human figures, with drawn or image references with the chiaroscuro technique as the focus. After the project, the student-sculptors were able to interpret the illusion of three-dimensionality in picture reference into the actuality of depth and volume during modelling, rendering compositions in its right planes or surfaces. The study recommends the application of the chiaroscuro technique in relief sculptural practices such as relief carving, repoussé, and other relief related sculptural practices.
