Through the photographer's use of various modeling methods, the shape, color, texture, three-dimensional, dynamic and spatial relationship of the subject are vividly displayed on the screen, so that it conforms to the human visual law. The golden section of photography is the intersection of two lines of a tic-tac-toe on the camera, and four lines are the golden section. This is the dividing line. Because putting people or things on these points is the best position of the whole picture, the composition called golden section line or golden section point is the processing and arrangement of picture modeling. In essence, it is to solve the internal relations and spatial relations between various elements on the screen, and organize them organically on a screen to form a unified whole. Therefore, for photographers, composition is an important link in the process of transforming natural "shape" into artistic "shape", focusing on conception and concrete expression methods. Photographic composition refers to the use of camera lens imaging characteristics and photographic modeling to form a picture to prompt some content. Broadly speaking, photographic composition runs through the whole photographic process, from the establishment of the theme to the completion and reproduction of the work. In a narrow sense, photographic composition refers to the structure and layout of the picture, including the selection of scenery and the handling of its position and size on the picture, as well as the handling of graphic factors such as tone, tone, line, light, reality and picture. In social practice and life, the subject matter of photography is extremely rich and extensive, so the composition is also varied. Beginners often feel at a loss when they learn photography composition. To learn photographic composition well, we should pay attention to the following aspects. ① Highlight the theme: When shooting, make sure the theme dominates the picture. For example, when shooting a scene where a model worker works, he has to occupy a larger picture position, and other people and things occupy a smaller picture. In addition, you can also use the contrast methods of distance, reality and light and shade to achieve the purpose of highlighting the theme. For example, shoot the main body and foil, so the theme is eye-catching and attractive. (2) Conciseness: All unnecessary scenes irrelevant to the theme should be discarded. When encountering complex scenes and scenery, the simplified ones will be simplified. (3) Picture unification: Sometimes there are many characters (or scenes) in a picture, so that the characters (or scenes) and other factors on the picture are not scattered and contradictory, and strive to be unified and avoid clutter. For example, the picture of a basketball game shows players running or jumping, but everyone's attention should be focused on the ball, so that the picture can be unified.
Question 2: What does the golden section mean? Qin Huang division is the ratio of the whole to the part: the ratio of the part to the whole is 0.6 18, almost three fifths, which is generally the most beautiful. . . For example, if you take a bust of a person, your head takes up two-fifths or three-fifths of the whole picture. If it is half, there is no beauty.
Question 3: How to draw the golden section in painting? What's the use? Painting is not only art, but also technology.
From an artistic point of view, painting needs to embody aesthetic feeling, thoughts and so on. How to embody these elements is something that needs technical content. You should have enough research on people's visual habits, including psychological activities. The golden section is the inertial thinking of studying human nature. A good work must have a distinct structure and clear priorities.
Question 4: What is the golden section of photographic composition? Can you elaborate on it? How? The golden section refers to dividing the whole into two parts, and the ratio of the larger part to the whole is equal to the ratio of the smaller part to the larger part, and the ratio is about 0.6 18. This ratio is recognized as the most aesthetic ratio, so it is called the golden section.
It is said that in ancient Greece, Pythagoras was walking in the street one day. Before he passed the blacksmith's shop, he heard the blacksmith strike the iron, so he stopped to listen. He found that the blacksmith had a regular rhythm in striking iron, and the proportion of this sound was expressed mathematically by Pythagoras. When a line segment is divided into two parts so that the ratio of the larger part to the total length is equal to the ratio of the smaller part to the larger part, this ratio is the golden section. The ratio is (√ 5- 1): 2, and the approximate value is 0.6 18, which is usually expressed by the Greek letter Ф.
Question 5: What is the golden section? And briefly describes its role in graphic design composition. Please mainly explain the function. Thank you. The golden section is almost a third of the plane composition. That is visually meaningful, that is, aesthetics ~ ~
If lz often looks at classic photos and paintings, almost all classic things conform to the characteristics of the golden section.
The specific golden section is 1: 0.6 18 or 1.6 18: 1.
Question 6: How to use the composition of the golden section line to stuff every object into the golden section point? For example, the height of a person and the corn in his belly are the golden section.
Question 7: The difference between the nine-grid composition and the three-point composition in photographic composition. Jiugongge composition: the picture is divided into nine small pieces with four lines. The intersection of these four lines is the golden section of the line.
Trigonometry: dividing a picture into three equal parts.
Jiugongge composition method
It is to put the main body or important scenery at the intersection of "Jiugongge". The four intersections of the word "well" are the best positions of the main body. Generally speaking, the intersection on the upper right is the most ideal, followed by the intersection on the lower right. But it is not static. This composition format is more in line with people's visual habits, making the subject naturally become the visual center, with the characteristics of highlighting the subject and making the picture tend to be balanced.
It is found that the four points where the four lines of Jiugongge meet are the most sensitive places for human vision. In foreign photography theory, these four points are called "centers of interest". As the name implies, it has been repeatedly proved that when the subject is at or near these four points, it is easiest to get the "eyeball".
Triangular synthesis
It refers to dividing the screen into three parts, and each sub-center can be put together with the main form. This composition is suitable for multi-modality parallel focus subjects. It can also represent large space, small objects, and vice versa. This composition is vivid and concise. It can be used in different scenes such as close range.
When observing the scenery through the viewfinder, imagine dividing the picture into three equal parts. The intersection of lines is the place where the interesting center and other minor scenery are arranged. Of course, this rule can be applied flexibly. The center of interest doesn't have to be exactly at the intersection, but it must be in that area. Those intersections at the right end of the picture are usually considered to be the strongest; Of course, the left third is sometimes used to arrange interesting centers, depending on how the picture is balanced. Trigonometry applies to horizontal and vertical frames. Arrange the subject and partner according to the three-point method, and the photos will be compact and powerful.
Question 8: What is the golden section in art painting composition? Golden section:
Divide a line segment into two parts so that the ratio of one part to the total length is equal to the ratio of the other part to this part. Its ratio is an irrational number, and the approximate value of the first three digits is 0.6 18. Because the shape designed according to this ratio is very beautiful, it is called golden section, also called Chinese-foreign ratio. This is a very interesting number. We use 0.6 18 to approximate it, and we can find it by simple calculation:
1/0.6 18= 1.6 18
( 1-0.6 18)/0.6 18=0.6 18
This kind of value is not only reflected in painting, sculpture, music, architecture and other artistic fields, but also plays an important role in management and engineering design.
Golden section:
More than 2000 years ago, Odox Sass, the third largest mathematician of Athens School in ancient Greece, first proposed the golden section. The so-called golden section refers to dividing a line segment with length L into two parts, so that the ratio of one part to the whole is equal to the ratio of the other part. The simplest way to calculate the golden section is to calculate the ratio of the last two numbers of Fibonacci sequence 1, 1, 2, 3, 5, 8, 13, 2 1, ... 2/3, 3/5, 4/8, 8/655.
Around the Renaissance, the golden section was introduced to Europe by * * * people and was welcomed by Europeans. They called it the golden method,17th century European mathematicians, and even called it the most valuable algorithm among all kinds of algorithms. This algorithm is called the three-rate method or the rule of three numbers in India, which is what we often say now.
Question 9: What is the golden section principle of camera composition? The golden section ratio of the subject in the whole image is 0.6 18! According to this ratio, countless groups of ratios such as 2: 3, 3: 5, 5: 8, 8: 13 are arranged.
