This drawing technique is often referred to as "shading from imagination," "rendering," or "scumbling". It is a method of building form by focusing on the interaction of light and shadow rather than strictly relying on outlines. Key details about this technique: Process: Instead of drawing a detailed contour first, you imagine a 3D overlay of the object and begin shading in the darkest areas, building up layers until the form becomes visible. Methodology: It often involves starting with general shapes, then defining the light source to determine where shadows should be. The artist uses circular motions, scribbling, or cross-hatching to build up tones. "Carving" the Image: This approach is described as "carving" the form out of the light by progressively darkening the shadows to create a 3D effect. Value Hierarchy: It requires a strong focus on the relationship between different tones (values), ensuring the darkest shadows and lightest...
