What are the basic principles of sketch and still life composition?

Sketching still life composition should pay attention to the balance of gravity, and the picture should be left blank with "less upper and more lower, balance left and right". In other words, there is less white space in the upper part of the whole picture, more white space in the lower part, and the left and right blank spaces are basically equal. Make the picture composition more reasonable and have a complete and stable visual experience. The composition should not be too full, nor should it be in space, and objects should not be placed loosely.

1, clear priority

The principle of composition needs to consider the visual center of the picture. The position of the main object is usually around the golden section of the picture, not in the center of the picture. The golden section is the first vision for people to see the picture. The area contrast and position layout of the subject and the secondary object are isomorphic, forming a visual effect. The contrast between the area of the main object and the area of the secondary object highlights the visual effect of the main object.

2. Full composition

Full composition refers to the proportion of objects placed in the paper, which makes the visual effect of the picture full of tension. The size of the object depends on the shape of the main object, and try to avoid the object from exceeding the border of the drawing paper. Full composition can make the picture attractive, and the objects in front and behind need to be separated in space.

3. Black, white and gray layout

The black, white and gray layout of the picture is also the main link of composition, which is very important to the black, white and gray layout of the object. First of all, heavy-colored objects need light-colored interlining, and light-colored objects need dark-colored interlining. Dark surfaces and dark objects should not overlap back and forth or left and right. Objects also need contrast between light and shade. In short, in the process of composition, we can follow the principle of "black dialogue, white to black".

4, light and heavy balance

The light and heavy balance of the picture is the relative balance of the object in the left and right and up and down, not the absolute balance. Put a group of still lives, with the main objects on the left, and generally put the larger secondary objects on the right, instead of putting all the larger objects on the left.

5. Points, lines and surfaces

A complete set of pictures must have the elements of "point, line and surface". The role of "points" is to embellish the picture; The function of "line" is to break the "whole" of the picture and make the picture more tense and elastic; The function of "surface" is to make objects expressive and complete. The combination of "point, line and surface" is the most basic component of a group of still life.
