​The effect of the composition of a picture

Photographic composition refers to the layout and structural arrangement of a picture. Although the most specific understanding of the meaning of photographic composition is different, canvas prints but there is one conclusion is the same, which is that PP with good composition is more attractive than PP with poor composition, more attractive and durable, and more able to convey the photographer's intention of expression. We can understand the effect of composition from the following aspects.

1. Picture effect of the shooting point

Photographic composition is the composition of the camera lens. The position of the camera lens on the subject is the shooting point. Different shooting point, canvas online australia the same scene in the picture on the effect is very different. Choosing the right spot can often be the key to a good photograph.

A. The picture effects of different shooting distances.

Different shooting distances will bring different effects to the picture, cheap large canvas and different scenes have different performance effects. Generally divided into the following:

Perspective: the subject has a broad and far-reaching range and is good at expressing the imposing manner of the scene. It mainly takes nature as the object of expression and emphasizes the overall structure of the scene while ignoring its expression.

Panorama: the scope of the subject is smaller than the perspective, and it is good at showing the whole picture of the subject and the characteristics of the environment. In contrast, a panorama has a more pronounced stereoscopic effect than a vista.

Middle shot: the scope of the subject is between the perspective and the panorama. It is good at showing the relationship between people and things, and wins with the plot.

Close shot: highlights the main part of the subject, the main face, is good at the character's demeanor or the main shape of the scene to do delicate description.

Close-up: a more focused representation of a part of a subject or scene. It is more detailed and detailed than a close-up.

B. The picture effects from different directions.

"Direction" means whether the shooting point is on the front, back or side of the subject. A change in the direction of the shooting point will not only significantly change the image of the subject, but also significantly change the background environment.

Frontal direction: the direction of the camera facing the subject. Good at the performance of symmetrical beauty, can produce solemn, dignified, quiet feeling. But the picture lacks perspective.

Oblique direction: it can make the horizontal line of the subject become a convergence line that can produce a strong perspective effect on the picture, thus helping to show the three-dimensional and spatial sense of the scene. The picture appears vivid, which is conducive to highlighting the subject.

Positive side direction: the side direction that is 90 degrees from the front of the subject. Often used to photograph characters, its features can vividly show the figure's face, especially the outline of the nose. But do not shoot the building, because it will weaken the three-dimensional building and the sense of space.

Backside: shooting from the backside of the subject. When shooting characters from the backside, if we pay attention to the use of posture, it will produce a kind of implicit beauty and make people think more.

C. The picture effects of different heights.

"Height" refers to whether the camera is above, below or at the same level as the subject.

Flat shot: the camera is positioned at the same height as the subject, with the camera shooting in a horizontal direction.

Backshot: the camera position is lower than the horizontal height of the subject, which is characterized by the upward shooting direction of the lens. The inverted shot helps to emphasize and exaggerate the height of the subject, but the lens should not be tilted too far, or it will cause serious distortion of the figure or scene.

Aerial shot: the position of the camera is higher than the horizontal height of the subject, which is characterized by shooting with the lens down. Its biggest characteristic is that it can make the front and rear scenes fully developed in the picture, which is helpful for the picture to produce rich scene layers and profound sense of space.

2. Modeling effect of light

Light for the position of the subject, namely the direction and Angle of the light, will produce different shading effects for the same object in different light positions. These points:

A. front light. The light comes from the front of the subject and is divided into flat light, direct light and high light. The main body of positive light illuminate can make the person feels very bright, but stereo feeling is poor.

B. front light. Side light at a 45 degree Angle. The subject and the character are animated and three-dimensional.

C. side light. Also known as 90 degrees side light, side light of the subject is Yin and Yang effect, can highlight the name of the dark contrast.

D. rear light. Also known as side light. The light comes from the rear of the subject and creates an outline on one side of the subject. Make the subject and background separate, so as to strengthen the three-dimensional sense of the picture and the sense of space.

E. backlight. Also known as backlight. The light comes directly behind the subject. It may cause the subject to produce vivid contour lines. Make the subject and background separate, so as to strengthen the three-dimensional sense of the picture and the sense of space.

F. toplight. Light comes from directly above the subject, as in the midday sun.

G, barefoot. Light comes from below the subject.

3. Visual effect of the subject

Composition, the most important thing is to shoot the protagonist (that is, the subject) should be placed in what position, this is the positioning of the subject. In a good PP, generally speaking, should use a most attractive visual attention center, namely "visual center".

In our common picture, the position of the visual center can adopt the "three equal method" of the nine grids to form the shape of the tic-tac-toe. In other words, two lines of vertical and horizontal lines are used to form the well-shaped character on a picture, and the four intersections of the well-shaped character are the best points to arrange the main position of the photography.

In order to achieve the visual effect of the picture, but also pay attention to the use of foreground and background. Foreground refers to the scene in front of the subject close to the lens. It helps the subject to reflect the seasonal and local characteristics, and prompts the audience to associate and create the effect of artistic conception. The background is the scene behind the main body of the picture. It is part of the picture, to set off the main body. Note that the background should be concise, to have a sharp contrast with the main body, it has the role of improving the visual effect of the main body.

4. Formal effect of lines

Once many objects in nature enter our lens, it is obvious that they form a line structure. Common compositions include the following:

A. triangle composition

There are many kinds of triangle composition on the picture, such as equilateral triangle, right triangle, equilateral triangle, inverted triangle, oblique triangle, side triangle, etc. Equable triangle has sedate, balanced, stable characteristic, and inverted triangle gives a person with not stable feeling, but have move feeling extremely, the stimulation of the vision is more intense. In addition, the "V" composition also belongs to the triangle composition.

B. s-shaped composition

S shape is actually a curve, belongs to the regular stereotypes curve, has the advantage of curve, beautiful and energetic and lasting appeal, and the picture appears lively, can effectively show the sense of space and depth of its scene.

C. cross diagram

The cross is the vertical intersection of a vertical line and a horizontal horizontal line. This composition gives a sense of stability, solemnity and seriousness. Can show mature and mysterious, healthy and up, but not easy to make horizontal and vertical equal length, generally vertical long horizontal short is good, if the length of the two lines are consistent, and the intersection of equal points, give a sense of symmetry, lack of vitality and dynamic, will reduce its expressive force.

D. Diagonal cross composition

The deformation of the cruciform is the composition of diagonal crossing. The original cross shape of the intersection of the two lines for the axis, slanting over will become two oblique lines, in the form of diagonal intersection of the picture and the former to reduce the symmetry of the mechanical, and more dynamic, more lively, stretch.

E. composition of rice pattern

The composition of "rice" is not only a "rice" shape, but also a multi-line intersection figure with an intersection point as the axis. It has a sense of unity and cohesion. Its lines are intersecting cohesion, a symbol of centripetal force, such as the two wings of a butterfly, so called "butterfly" composition.

F. frame composition

Frame composition is to show the main body, with the nearest from the lens of the bushes, flowers and plants surrounded in the center, so that the foreground form a "frame", so that the audience through the frame to appreciate the main body, this PP should pay attention to the frame and the main body to have a strong contrast between the shade or virtual reality.

G. Bestrew composition

It not only refers to the use of a single subject to fill the picture, to highlight the main body, but also refers to a large number of subjects to fill the picture, leaving no blank. As the image of the subject is crowded to the brim, so there will be no imbalance or sedate problems, will give people imagination, the line of sight to the screen.

H. Diagonal composition

Diagonal composition refers to the relationship between the four corners of the drawing surface and the role of diagonal. It also refers to the composition form in which objects create diagonal lines in the picture to make the picture come alive.

Diagonal line can guide people's line of sight and form a dynamic, let the picture increase vitality, so that the fixed image changes. In addition to the use of diagonals in the picture, the scene can also be used to create diagonals in the picture. There are many ways to create diagonals, such as tilting the picture, selecting the shooting Angle, using perspective and so on.

I. making directional angular composition

Orientation Angle is to create an Angle intentionally in the picture. Different from diagonal composition, it is to create one or several angles in the picture to show the direction of movement. The smaller the Angle, the greater the impact; The sharper the Angle, the more dynamic. This composition creates an atmosphere and enhances artistic expression. Dip-angle composition can be used not only for buildings, but also for other groups of characters and scenes to create angles.

J. Composition of central convergence form

Convergence in the center means that all the lines in the painting converge to the center, forming an intersection and drawing the audience's attention to the convergence center. This kind of composition besides want to reflect the line that faces far away, should arrange main body scenery on the position of convergence point, do not form the situation that convergence does not have advocate.

K. Symmetrical composition

Symmetrical shape composition refers to the same or similar formal factors in the scene, which are expanded or combined by corresponding relations on both sides of the central axis. Symmetry, it requires that the left and right sides of the picture or both ends of the upper and lower ends have the same object corresponding to each other, or the object is not exactly the same, but its size is proportional, corresponding to the position.

5. Emotional effect of shadow tone

In real life, due to the different conditions of light irradiation, objects absorb and reflect different characteristics of light, have different colors and brightness. The picture will show the change of light and shade of the scene, so that we can understand the shape, volume and texture of the scene. For example, in the lightest to darkest shadow tone, different shades of shadow tone levels are more, the transition trend is slow, such called "soft tone", on the contrary, called "hard tone", in between called "middle tone". Black and white tonal the proportion that holds a picture is different can form different sense again. Some are "high profile"; some are "low profile". Color photos: warm tone, cool tone, contrast tone, harmonious tone and so on.

In this colorful color tone, it gives a psychological emotional, symbolic, panoramic prints online functional feeling effect. For example, in different colors, warm colors make people feel close and warm. Cool colors make people feel distant and cool.

6. Comprehensive artistic effect

Synthesizing the above points, according to the comprehensive configuration of shooting point, light, main body, line and tone, PP produces rich artistic effects in picture modeling, vision, form and emotion.
