What are the artistic effects of backlight photography?

First, it can enhance the texture of the subject. Especially for shooting transparent or translucent objects, such as flowers, plant branches and leaves, backlight is the best light. Because, on the one hand, backlight illumination can improve the brightness and saturation of transparent objects, and dim transparent or translucent objects under forward illumination show beautiful luster and good transparency, which increases the effect of light transmission and brightness enhancement; On the other hand, the brightness difference between transparent and opaque objects in the same picture is obviously widened, and the light and shade are opposite, which greatly enhances the artistic effect of the picture.

Second, it can enhance the rendering of the atmosphere. Especially in the morning and evening of landscape photography, the light and shadow modeling method with low angle and large backlight is adopted. Reflection paints rosy clouds as dyes, clouds as transpiration, and mountains, villages and trees as ink paintings. If mist, canoes and birds are added, it will cause a deep sound in vision and psychology, which will make the work deeper in connotation, higher in artistic conception and stronger in charm.

Third, it can enhance the visual impact. When shooting in reverse light, due to the increase of the proportion of dark parts, quite a lot of details are blocked by shadows, and subjects with simple lines or small light receiving area suddenly appear in the picture. This large light ratio gives people a strong visual impact, thus producing a strong artistic modeling effect. Specifically, first of all, the background can be under backlight, with insufficient exposure and poor color reproduction, so that the background can be purified, thus achieving the effect of highlighting the subject; Secondly, it can vividly outline the clear outline of the subject, separate the subject from the background, highlight the ups and downs and lines of the subject, and strengthen the subject's sense of subjectivity; Third, it can profoundly portray the character. Because the light receiving area of the whole picture is small, most of the face and body are in shadow, forming a dense low-key picture dominated by dark colors, which is helpful to express the deep, implicit, solemn or melancholy character of the characters. At the same time, due to the large color contrast and strong light and dark layout, some flaws in the face of the characters can be diluted by strong light and covered by the shadow of backlight, thus achieving the effect of fostering strengths and avoiding weaknesses.

Fourth, the depth of the picture can be enhanced. Especially when shooting in the morning or evening with backlight, the color composition has changed from far to near due to the different media conditions in the air: the foreground is dark and the background is bright; The foreground color saturation is high and the background color saturation is low. In this way, the whole picture from far to near, color from shallow to deep, from shallow to deep, forming a subtle sense of space depth.
