1. First, visit the gypsum geometry in a certain way, which needs to be patchy and well-balanced.
2. Place the drawing board, fix the sketch paper on the drawing board, and put the spotlight on the side of the gypsum geometric combination, so that the light source can fully divide the light and shade.
3. Start forming. It is required to first investigate the perspective relationship and pay attention to the interactive relationship between the near big and the far small, the near real and the far virtual. At the same time, we should pay attention to the intersection of perspective and line of sight level.
4, a comprehensive observation of the layout, reasonable composition, need to set aside a certain space around the picture. When molding, first draw the external shape of the geometry, and then describe its deconstruction trend, so as to describe the shape most accurately!
5. After molding, it is to lay the tone and draw the relationship between light and shade. First, the whole dark side is displayed, and the tone is single and does not need to be changed. Then, the gray side is the layout, and notice the contrast between the two tones.
6, depicting the dark side, the projection should be different from the dark side of the geometry itself. It is suggested to add a light level to the bright side, and then simply spread the background. So there are two levels of bright side and dark side. Be sure to pay attention to the dividing line between light and shade, don't draw it too rigidly, and "pile" it out many times with soft lines instead of "carving" it out.
7. Start drawing the intersection of light and dark, and add a small gray surface to the bright surface. In the process of painting, you can put the drawing board far away and squint at the overall effect to avoid "greasy" and "dirty" situations.
8, step by step, until the overall effect is completed.
9. In-depth description of details, such as potholes and broken corners on plaster statues, folds on the backing, etc. , make the picture more exciting, and constantly fine-tune the relationship between light and shade!
