Tone of photographic composition method

In the formal expression of photographic composition pictures, especially in color photography, color plays an extremely important role in rendering pictures to express atmosphere and convey some information. In addition to lightness, there are many factors that make up the tone of a picture, such as hue, purity, temperature, area, light and so on. Generally speaking, the composition of hue first depends on which color has the largest area in the picture. Large-scale and dominant colors can form the main tone of the color relationship of the picture. In this clear theme, it is divided according to other colors in the arrangement picture. In the color circle, the colors that are close to each other have a strong sense of harmony, and the colors that are far away have a strong contrast. Usually, it is customary to divide the hue relations of different distances and angles into the same color from small to large (the distance in the color phase ring is 15). The hue contrast around the corner), adjacent colors (the distance in the color phase ring is 45. Angle of hue contrast), different colors (the distance in the color circle is 120. To 197. The hue contrast between them), complementary colors (the distance in the color phase ring is 180. Angle of tone contrast relationship).

The color relationship with the strongest hue contrast is 180. Corner complementary color. The contrast of similar colors can be regarded as a harmonious effect in tone and a link between colors.

For the tone composition of color pictures with small volume difference in color relation but far apart in color phase ring, the same color factor is introduced into the contradictory and contrasting color relations respectively, thus producing different color relations, thus producing a certain * * * personality and forming tone. For example, white, gray or black, blue, yellow, red and green, added to a pair of exciting complementary colors, can produce harmony.

(1) Mix the same color with different colors, thus strengthening the "blood relationship" of its appearance.

② In heterogeneous color pictures, the same color is used for decoration and embellishment, thus forming the visual assimilation effect of color.

(2) The same color is coherent around the heterogeneous color area, so that the colors with strong contradiction cannot be directly contacted.

(4) Add some colors between different colors in the color circle in the picture, which can play a role in reconciling and gradually changing the contradiction of different colors.

The purity relationship of colors also has a strong influence on the tone formation of different color relationships, and the same hue gives people different feelings because of different purity. In the expression of hue, the cooperation of different purity relationships can form the richness of hue.

In the form of photographic composition, the determination of hue should be based on images. According to the expressive function of picture form, it is necessary to combine the law of formal beauty and comprehensively consider various relationship factors to make color tone the expressive language of picture form.
