Ke Yizheng’s 2022 Fall NAG Nature Apprenticeship Theory Lecture is a full semester of the core principles behind his painterly, classically inspired digital work. Over 14 classes the course builds from core theory and training methods through black and white tonal values, comparison, plaster cast sketching and modeling, elasticity and solidity, and portrait structure, then moves into abstract environments, hue, gray versus pure color, color style and contrast, natural scenery and shape comparison. Each topic is reinforced with step-by-step demonstrations, from still life flowers and fabric folds to a four-part plaster statue, a four-part sketch portrait, color portraits and a lakeside landscape, along with regular Q&A sessions, a talk on creative experience and a semester summary.
