How to draw and use the golden section

How to draw and use the golden section is as follows:

The golden section is a mathematical proportional relationship that is commonly used in the fields of art, design and photography. It is widely recognized as a compositional method that brings harmony, beauty and balance to a work. The following is a detailed description of how to draw and use the golden section:

Drawing method:

1. Prepare drawing paper or canvas and determine the graphics or images to be drawn.

2. Select one side as the baseline and mark a line segment with a length of 10 units.

3. Divide this length into two parts, namely 8 units and 2 units (or according to the ratio of 1:1.618).

4. Starting 2 units from the baseline, draw a line segment perpendicular to the baseline.

5. Divide the length of this line segment into two parts again, namely 5 units and 3 units (or according to the ratio of 1:1.618).

6. Draw another line segment 3 units from this line segment perpendicularly to the baseline.

7. You can continue to repeat the above steps and continue to divide the line segment into two parts of the golden ratio.

How to use:

1. Split composition:

In painting or design, you can use the golden section line to divide the picture or image into two parts. Make the overall composition more coordinated and harmonious. By placing important elements on the golden section, you can attract the audience's attention and enhance the visual impact.

2. Displacement:

By placing objects or elements at the intersection of the golden section, you can effectively guide the audience's gaze and create a more dynamic and interesting picture effect.

3. Proportion control:

According to the golden ratio, the size and proportion of graphics, objects or elements can be controlled to make them more in line with the aesthetic feeling of the human eye.

It should be noted that the golden section is only a guiding principle, and it is not necessary to follow a strict proportional relationship when creating or designing. It should be viewed as an aid to provide a reference for symmetry, balance and beauty rather than as a fixed rule. Ultimately, the creator should determine whether to use the golden section to compose the picture based on the actual situation and his or her own aesthetic judgment.
