(1) The bridge of nose composed of nasal bone and cartilage;
(2) The oval nose ball and the nasal septum below it;
(3) The two alars are inclined outwards and downwards, and the nostrils are hollow. The whole nose is like a trapezoid with a narrow top and a wide bottom. In the performance, we should pay attention to the changes of its four parts (see Figure 28).
(1) nasal root. This part consists entirely of nasal bones. Near the double-tear mound, the upper end is connected with the downward curvature of the frontal bone. The root of the nose is the narrowest part of the nose and the most "urgent" turning point. Its contact with the eyes is also very sudden. So the contrast in this part changes greatly. But because it is too close to the eyes, don't emphasize its changes too much when painting, so as not to weaken the performance of the eyes. Usually, it only emphasizes the contrast relationship near the eye structure.
(2) the bridge of the nose. This part consists of the lower end of the nasal bone and two nasal cartilage. It is located in the middle of the nose, which is about a standard trapezoid with three obvious planes on both sides. To describe this part, we should not only pay attention to the shape and structural changes of the three planes, but also pay attention to the sense of mass of the whole trapezoid and the embedding mode of its adjacent parts.
(3) the nose part. It is completely composed of nasal cartilage, which is divided into two parts: the tip of the nose and the alar. The tip of the nose looks like a sphere, and its two wings look like hemispheres, so it is obviously different from the trapezoid of the bridge of the nose in physical characteristics. This part is the highest point of the portrait face, which is far from the eyes. It can be used as the second focus of the face and described in detail.
(4) the bottom of the nose. This part is actually the bottom of the nose. Because it is in sharp contrast with other parts of the nose in shape after receiving light, we are used to treating it as a special part. The physical feature of this part is the complex structure formed by the turning surface of the tip of the nose and two nostrils. When the steering angle is greater than 90, the whole nasal floor is in darkness, forming an obvious dividing line between light and shade. Two irregular nostrils produce complex reflections around them, and these reflections and the boundary between light and shade are the difficulties in nose performance. When describing it, we should pay attention to its rich light and dark changes and reality.
The nose is the largest part of the face, which makes the face have strong light and shade changes. The method of depicting this part is flexible, which can not only emphasize the role of light and shade, but also emphasize the role of structure: it can strengthen the treatment or weaken the treatment. The shape of the nose varies from person to person and is an important part of a person's physical characteristics. In the performance, we must first master its overall image characteristics, and then make a local description.
