How to understand harmony in photography?

Color harmony refers to the color configuration of the whole picture, which should be unified and coordinated, and complete and pleasing to the eye. This is done through the rational allocation of colors and the arrangement of the relationship between colors. There are several requirements for color harmony: 1. When taking color photos, the color tone should be determined according to the needs of the theme, which plays an important role in setting off the theme, expressing the environment and atmosphere, and conveying the author's mood and artistic conception. In a work, the arrangement of all colors should be consistent with the tone of colors. Compared with hue, other colors can only play the role of foil and foil, which is the relationship between part and whole. If the tone violates this integrity, the work will present a disharmonious tone. The unity of hue does not mean the monotony of color expression, nor is it just the patchwork of colors, but the richness and diversity of colors in the works, which is a regular unity. Only in this way can the works give people a perfect visual experience. 2. Harmony of colors When arranging colors, appropriate configurations should be made according to the saturation, brightness, light and shade of colors on the screen, as well as the number and area of colors, so that the whole screen has a unified and harmonious effect. The same hue has colors with different lightness, which is easy to reconcile, but when two colors with higher saturation are matched, it is not easy to reconcile because of the large color jump. In this case, the purity of one color should be lighter or thicker, and the main bodies of the two colors can also be separated by a certain distance. The near scenery is thick and the far scenery is light, so as to conform to the due perspective relationship. Between the two colors, intermediate colors can be used to buffer the transition, and achromatic colors such as white, gray and black can also be used to divide. Due to the difference of lightness and saturation, the color changes from bright to dark, from thick to light, and the color can also be reconciled with various gradual changes. In color matching, the colors with small lightness and strong lightness should be used alternately with those with large lightness and light lightness. There are shades in light colors, and there are light colors in shades, so that the shades are appropriate, harmonious and varied. In the arrangement of colors, we should not arrange colors just for the sake of color arrangement, but also consider the overall relationship of colors; In the layout of colors, the number and area of colors should be changed and balanced to avoid equal rows. Colors should be divided into primary colors and secondary colors. One color should be the main color, and other colors can only play an auxiliary role. If the whole picture is blue, the color will appear elegant; If it is only this hue, the picture will appear monotonous; If there are one or two small yellow or red decorations in the picture, the whole picture will come alive; If the area of yellow or red is too large, it will destroy the tone integrity of the whole picture. Therefore, to master the quantity and area of colors, it is necessary to play a coordinating role and make the whole picture achieve a balanced and stable effect. 3. color care color care means that in a work, in order to achieve comprehensive harmony of colors, we must also take care of the contrast and care relationship between colors. The nature of color is unstable and interdependent. In a certain space and time range, it will change because of the influence of adjacent colors. Next to the green, there is a piece of red with obvious color; Match a piece of red next to the pale red, and the color is harmonious; In the sun, red is bright; In the light, red is dim. If the red object is covered with green tulle, the color will be colder; If the black veil is covered on the red object, the color will get warmer, indicating that the color is changed by external influences. When configuring colors, we should consider the relationship between colors. There should be no obvious conflict when various colors are matched with each other. Dark colors can set off bright colors, and without dark colors, there will be no characteristics of bright colors. When configuring colors, the number and proportion of bright and dark colors, warm and cold colors, shades and soft colors should be considered together. Only in this way can there be differences in configuration and different harmonious effects be formed.
