Children's photography, how to use indoor lighting, solutions

1, main light. The main light is the first choice to determine the lighting mode of children, and other lights can only play an auxiliary role. The main light used in modern studios is usually emitted by soft light boxes. Soft box should be used, because the light it emits is more uniform and easy to control. The so-called soft light box is actually to put one or several light bulbs in a box and illuminate children through a soft light box cover that can scatter light. The bigger the box, the more light bulbs, the stronger the power and the wider the lighting range. For the general photo studio, a soft light box with a diameter of about one square meter can be competent. The distance and angle of illumination can be adjusted as needed, and the exposure is determined according to the main light.

2, fill the light. Fill light, also called auxiliary light, as the name implies, its function is to supplement the light of shadow and make it shallow. The auxiliary light can be the same soft light box as the main light, and the light ratio between it and the main light can be adjusted by illumination distance or output power. If the exposure of the supplementary light is 3 stops less than that of the main light, then its light ratio is 1: 3, which means that the result will get a deeper shadow. If the intensity of the supplementary light is close to the main light, for example, the difference is half an aperture, then the shadow part becomes very shallow. For simplicity, the light source can be fixed on the ceiling or wall, and the depth of the shadow can be controlled only by adjusting the output power. Therefore, how to get the optimal light ratio between auxiliary light and main light can only be achieved through repeated experiments.

3. Background light. In most cases, children will distance themselves from the background. Because with the increase of distance, the illumination of the light source is obviously weakened, and the background is farther away from the light source than children, so the brightness of the background is much darker than children. If exposed according to children's lighting, the background will appear darker, and as a result, children will look as if they are integrated into the dark background. So in order to distinguish the children from the background, it is necessary to illuminate the background separately, so there is the so-called background light. The use of background light should pay attention to the color, distance and lighting angle of the background. Otherwise it will be self-defeating. Therefore, it is necessary to adjust the background light repeatedly to use it normally. In order to illuminate the seamless background evenly, it is sometimes necessary to use two lamps.
