sketch paintingThere were many key points in sketching:
** 1. Picture composition **
1. ** Triangle composition **
- This was a common and stable composition method. Divide the still objects into three groups and place them on three vertexes, suitable for combinations with fewer still objects. The picture was stable, the main object was prominent, the layers were clear, and the arrangement was orderly. The three sides of the triangle were formed by straight lines from different directions. The triangle formed by different lines would have different trends and changes. For example, sitting in the middle of a still life might use this composition more often.
2. ** C-shaped composition **
- The picture was more dynamic than other composition forms. It made the picture fluid and easier to express the still life combination in a larger space. There were three points. The main object was always in the middle point, the first point was where the first object was placed, and the last point strengthened the transition of spatial levels. It was usually used when painting while sitting on the side of a still object.
3. ** S-shaped composition **
- It had the advantages of beautiful curves, vitality, and charm, giving people the enjoyment of beauty. The picture was vivid and lively. The reader's line of sight moves along the "S" shape, which can effectively express the sense of space of the still life scene. Usually, the upper part of the'S 'would be shortened and the lower part would be lengthened, forming a composition relationship of' tight at the top and loose at the bottom'.
4. ** Circle composition **
- The still life was circled in the picture, giving the aesthetic effect of rotation, movement, and contraction. When the circle was elongated into an oval composition, most of them used the form of a banner that was wider than the height. There were static and dynamic effects, and there was a clear sense of unity.
5. ** Horizontal composition **
- It made the scene stable and peaceful, enhancing the sense of stability. The object should be in an upper or lower position. There were fewer spatial layers in the vertical direction. In order to make the picture rich, the various objects had to be contrasted in terms of shape, size, height, color, and other factors. At the same time, the positions had to be arranged to form the spatial layers before and after.
** 2. In terms of structure **
1. ** Character structure **
- For the study of the basic structure of the human body,"The Burgman's Teaching of the Human Body" was a good book. It described and described the structure of the human body in detail, which was beneficial for sketching and sketching.
2. ** Still life structure **
- In addition to systematic learning, the main focus of observation methods should be on the structure of the object itself. Finding the frame that supported the object was to find the structure. Not only did he have to study and analyze the places that he could see clearly, but he also had to study the places that he could not see clearly. He had to develop the habit of observing things in his daily life, observing everything in all directions.
** 3. Drawing steps (using different objects as an example)**
1. ** Steps to draw a character (Take the side portrait as an example)**
- First, draw a vertical line segment to represent the length of the head. Find the upper eyelid at 1/2 of the line segment. The eyebrow is slightly higher than the eye. The hairline is located at 1/2 of the eyebrow to the top of the head. The bottom of the nose is located at 1/2 of the eyebrow to the chin. The face width is about the length of the eyebrow to the chin. The bottom of the silkworm is located at 1/2 of the eyebrow to the bottom of the nose. The inner corner of the right eye is located at 1/2 of the face width. The length of the right eye is slightly shorter than 1/4 of the face width. According to the perspective law, the width of the eye distance is larger than the width of the left eye and smaller than the width of the right eye. The inner corner of the eye extended downward to the right side of the nose. The width of the nose was equal to the width of the right eye. The edge of the lower lip was located from the bottom of the nose to the chin. The middle between the bottom of the nose and the lower lip was the upper lip edge. The turning point on the right side of the chin was located on the vertical line of the inner corner of the eye. Then, he used a long straight line to outline the shape of the face, and compared the corner of the jaw with the mouth. Then, he used a short straight line to outline the general shape of the facial features. After that, he drew the outline of the hair and the relationship between the head and neck, erased the excess auxiliary lines, and then drew the shape of the facial features in detail to increase the structure and the relationship between light and dark.
2. ** Peanut Painting Steps **
- First, he drew the outline of the peanut, paying attention to the shape of the object. Then, he drew the general features, and the lines clearly outlined the basic shape. Then, he simply drew the light and dark relationship, and gently laid a layer of color. Then, he laid the tone according to the shape of the peanut, paying attention to the relationship between black, white, and gray. He drew the texture of the peanut skin, starting from the dark part and paying attention to the light and dark relationship. Finally, he drew the texture of the peanut skin as a whole, paying attention to the relationship between black, white, and gray.
3. ** Apple Basket Drawing Steps **
- First, he observed the general shape and gently drew the outline. After erasing the auxiliary lines, he drew a clear outline. Then, he laid out the general color tone and drew the relationship between the light and dark of the apple to give a three-dimensional feeling. He drew the apple basket in depth and paid attention to the relationship between the light and dark to draw the details clearly. He began to draw the apple and the fruit basket in parts to increase the color tone of the overall painting. He emphasized the inherent color of the fruit basket, highlighted the weaving line, and pulled away the relationship between the dark part and the gray part. He made in-depth adjustments to the fruit part as a whole, separating the light and dark sides to further draw the details; he drew the apples in the fruit basket in depth, paying attention to the increase in the color tone of the apples to increase the three-dimensional effect; he continued to draw the woven texture of the apple basket.
4. ** Eggplant Painting Steps **
- Use a 2B pencil to draw a rectangular shape and find the specific shape of the eggplant. Depict the eggplant. Use a 2B pencil to deepen the boundary between light and dark and transition gray to the dark and bright parts. At the same time, draw the color of the dark part of the eggplant handle and arrange it according to the shape structure. Depict the eggplant in depth. Use a 4B pencil to continue to deepen the color of the boundary between light and dark. The gray of the reflective part should be light. Draw the relationship between black and white. Depict the bright part. Use an HH pencil to transition from gray to the bright part. The transition between black and white should be even. To draw the eggplant handle, use a 2B pencil to deepen the boundary between light and dark and transition to the dark part. Use an HH pencil to draw the gray part of the light. Draw slightly harder where there are wrinkles, paying attention to the relationship between light and dark on each surface. To carve the projection, use a 2B pencil to arrange the lines from the root of the eggplant, and rub it with a tissue to make the actual and false changes.
** 4. Tools (Take a pencil as an example)**
- In the process of drawing, such as drawing an eggplant, different types of pencil had different uses. The 2B pencil could be used to draw the shape and some dark parts and details (such as the basic shape of the eggplant, the black and pleats of the pants, etc.), the 4B pencil could be used to deepen the boundary between light and dark and the color of the dark parts (such as when drawing the eggplant in depth), and the HH pencil could be used to draw the bright parts and transition gray (such as drawing the bright parts of the eggplant from the gray to the bright parts).
