How to arrange the lighting for photography indoors?

The so-called arrangement of light means the arrangement of artificial light. The light is arranged to use light, specifically flash and continuous light can be used. Shooting scenery and indoor portraits pay attention to the arrangement of light, including illuminance, lamp position, lamp number, lamp type, etc.

For illuminance: the main illuminance should be higher than the secondary light. According to the inverse square law of illuminance, the distance between the lamps is doubled and the illuminance is reduced to 1/4. Using different illuminances can create different light ratios and obtain different shades.

For lamp position: select lamp position by object. Children and women use forward light and front side light; the elderly and men use side light and side light. Two lights cross lighting. The front cross light can eliminate the subject's projection, and the back cross light can make the subject out of the background. The illuminance of the two lights can be different to make the picture distinct. Three-point lighting. The main light, auxiliary light, and backlight are commonly used in indoor portraits to achieve the ideal comprehensive lighting effect.

For the number of lights: According to the creative intention, you can flexibly choose single, double or multiple lights. Single lamp can create shadows, double lamps can increase or decrease shadows, and multiple lamps can form shadowless light. The more the number of lights, the more complex the light and the more difficult it is to control.

For the lamp type: the main light energy controls the tone, the supplementary light energy is insufficient, and the contour light energy creates a beautiful contour bright line, which modifies the light energy to beautify the part.

For the sequence: if there are two lights, they should be arranged in the following order: main light → secondary light. If there are multiple lights, they should be arranged in the following order: main light→secondary light→contour light→background light→decorative light.

For the light ratio: the light ratio of the secondary light to the main light for indoor portrait photography, generally 1:3 (high key), 1:4 (middle key), 1:5 (low key). Or the intensity of the secondary light should be 1/2, 1/3, 1/4 of the main light. The brightness of the main lamp and auxiliary lamp can be adjusted by setting the main lamp and auxiliary flash index.
