Unifying the dark side, this step is mainly to open the big light-dark relationship of the object, which is divided into three sides: dark side, projection side and bright side, so that the three sides form a strong black-and-white contrast relationship. Arrange the cables neatly, distinguish the dark side from the projection, and compare the colors of the desktop and the background.
Adjust the black, white and gray of the picture. The technique of this step is mainly "wiping". Use a soft paper towel or pen to unify the lines on the dark side of the object. Wipe the dark part and projection of the object first, then wipe the desktop and background. After wiping, adjust the dark relationship (the actual situation of boundary line and projection line).
In-depth shaping takes more than an hour to shape, starting with the main objects, paying attention to the spatial relationship and the primary and secondary relationship, and emphasizing the three aspects of black, white and gray, distinguishing the color and texture of each object, and adding details to enrich the picture. The main object needs to be portrayed, the color of the jar needs to be deepened, and some details need to be found to show the outstanding volume, which needs to be represented by delicate and neat lines. When describing the whole, we should distinguish the relationship between before and after, the relationship between primary and secondary, and the relationship between reality and reality.
