Features: is a scientific training method for sketching, and the main approach in traditional academic painting education. The plaster bust is white in color, with fine texture, simpler and softer in hue compared to real people, and has clear relationships between light, dark, and gray tones. It is suitable for long-term research and training, making it convenient for beginners to familiarize themselves with and master spatial structure and light changes, laying a solid foundation for future portrayal of real people.
(1) Composition: Generally, the composition of a plaster bust requires a complete image, with the bust arranged in a suitable position in the frame. It is also necessary to consider the balance and visual rationality of the composition.
(2) Light and Shadow Relationship: The plaster bust, under light exposure, produces different light and shadow relationships from different angles. As the structure rises and falls, the angles of light on the surface of the bust vary, resulting in different light and dark relationships (black, white, and gray). To accurately analyze and compare the light and shadow relationships of the bust, one must grasp the undulations and transitions of the plaster, paying attention to the changes in the light and shadow ( is the boundary between light and dark on the surface of an object, representing major structural transitions. It is not directly illuminated by the light source or affected by reflections, so its color tends to be darker. At the same time, attention should be paid to the changes in clarity and obscurity, thereby effectively conveying the structure, spatial sense, and layers of the plaster bust.
(3) Structure: The structure of the plaster bust does not change with the variation of light. When depicting it, one must focus on the structure and not blindly copy the tones. Only with a certain understanding of human anatomy can one accurately grasp the changes in bones and muscles, thereby accurately portraying the structural features of the plaster bust.
