What is strong light and what is soft light?

(1) Strong light (also called direct light) \x0d\ 1. Strong light The so-called strong light refers to strong direct light. \x0d\ 2。 Modeling effect of hard light: under the irradiation of hard light (direct light), the object has light receiving surface, backlight surface and shadow, which is an effective effect to form the three-dimensional shape of the object; The brightness distance between the light receiving surface and the backlight surface of hard lighting is relatively large, that is, the inverse size of the scene can cause strong contrast between light and dark, which is suitable for expressing rough surface texture; This modeling effect makes the lifted object form a clear image in outline form. This light effect can achieve both "strength" and "hard" artistic effect. \x0d\ can form shadows under strong light (direct light). The shadows of some scenes are very expressive, which not only increases the depth perspective of the picture, but also forms a rhythmic rhythm in the interval between bright parts and light and dark, which increases the appeal of the beauty of the picture. \x0d\ Taking a portrait with hard light (direct light) as the backlight will produce contour light with aesthetic effect around the figure, and the figure's face will be supplemented with soft light to form a harmonious lighting effect. When taking this photo, be careful that the auxiliary light on the front is not too bright. If it is too bright, it will weaken the light effect of backlight lighting and make the light feel unreal. \x0d\ strong light lighting, due to excessive contrast between light and shade, has strong color tone, especially in the dark part, which will damage the color, quality and even shape to a certain extent. \x0d\ In the photo studio or studio, hard light is generally not used as auxiliary light, because hard light will produce shadows, which are in contradiction with the shadows formed by Wang Guang, not only destroying the overall modeling effect, but also being unreal. There are two direct light sources in the environment, especially when Wang Guang imitates sunlight, it is even more inappropriate to use hard light as auxiliary light, because the two shadows will make people misunderstand the appearance of two suns. \ \x0d\\x0d\ (2 2) Soft light \x0d\ 1. Soft light refers to light that does not have obvious shadow on the subject. It is diffuse reflection, and the directivity of the light source is not obvious. \x0d\ 2。 Modeling effect of soft light. Soft light (scattered light) has soft lighting quality, no obvious light receiving surface and backlight surface, no obvious shadow and soft contrast, so the color tone is flat and soft; Generally speaking, the area of soft lighting is large, the light is relatively uniform, and the brightness of the illuminated scene is relatively close, so the hierarchical tones on the screen are relatively rich; Soft lighting is dull because of the lack of contrast between light and dark, so it has a three-dimensional effect on the subject. The performance of texture is also weak, and the performance of a given figure depends on the difference and contrast between the color of the subject and its own light and shade. It is suitable for expressing smooth surface texture. Therefore, under soft light (scattered light) illumination, the color and light-dark structure of the subject are very important.
