The Method of Drawing Face in Sketch

Make good use of "three courts and five eyes"

Santing: refers to the proportion of facial length, which is divided into three equal parts, from forehead hairline to eyebrow bone, from eyebrow bone to nasal bottom, and from nasal bottom to chin, each accounting for 1/3 of facial length.

Five eyes: refers to the proportion of face width, which is divided into five equal parts by the length of eye shape, from the left hairline to the right hairline, which is five eye shapes. There is an eye distance between the eyes, and the distance from the outside of the eyes to the hairline is one eye, each accounting for 1/5.

We make a vertical axis in the middle of the face through the forehead-nose tip-person-chin; Make a horizontal line through the eyebrow arch; Draw a parallel line through the lower edge of the nose. In this way, two parallel lines divide the face into three equal parts: from hairline to brow line; From the eyebrows to the lower edge of the nose; From the lower edge of the nose to the tip of the chin, the upper, middle and lower parts account for just one third, which is called "three courts".

And "five eyes" refers to the outside of the corner of the eye to the edge of the hairline on the same side, which is exactly the length of one eye, between the two eyes, it is also the length of one eye, and the other side to the edge of the hairline is the length of one eye. This is the "five eyes". This is the most basic standard.

Sketching skills:

(1) line and line technology

The element of sketch is a line, but the line does not exist in essence. It only represents the boundaries of objects, colors and planes as the illusion of objects. Until modern times, lines were considered as spontaneous formal elements, independent of the depicted objects.

(2) Use lines to form the image of objects.

Sketch is to form the image of an object with lines and draw it on the plane, that is, the line form causes the viewer's association. For example, the angle formed by the intersection of two straight lines can be considered as the boundary of a plane; In addition, adding a third line can create a three-dimensional effect on the screen. Curved lines can symbolize the vault, and intersecting lines can express the depth.

(3) Use lines to distinguish between solid and plane.

In sketch, lines can be used to distinguish between solid and plane, while color shading is to strengthen and distinguish the relationship between the whole and the part. We can draw the boundary with the beginning, disappearance and interruption of lines to form a plane, or we can let the colors reach the boundary. The thickness of lines can show the changes of objects, and even light and shadow can be shown through the changes of strokes of lines.

(4) The assistance of plane technology

The line technique of sketch also needs the assistance of plane technique. When charcoal chalk is used in plane technology, brush wiping can be used in contrast between light and shade.

(5) the use of brush painting

It is more important to use the brush painting method, because the brush can play the width and strength of strokes, and can increase the sense of space and three-dimensional sense.

(6) Enhance artistry

Sketch can also use multi-color brush as the basic material to enhance the sketch effect and artistic quality.
