How to use indoor light to shoot a good portrait?

It is difficult to adjust the light ratio when shooting portraits indoors, because the light irradiation direction is fixed, the difference between light and shade is large, and the brightness is lower than that outside. Therefore, pay attention to the following points:

A, indoor spotlight light and shade changes

Indoor spotlights are generally much dimmer than outdoor light. The brightness of indoor figure 2 is determined by the light incident from the door or window and the light reflected from the surrounding walls. There are many big doors or windows, and there is a lot of incident light. The wall is bright and clean, with light color and strong reflected light, so the brightness of the characters is large, and vice versa. In addition, with the change of morning, noon and afternoon time, the indoor spot brightness will also change constantly. Therefore, the exposure should be measured according to the brightness of the light received by people.

Second, the brightness difference of characters.

Indoor scene light enters from doors or windows, and its intensity determines the contrast between light and shade of photos. Generally speaking, the closer a person is to a door or window, the greater the brightness difference; The brightness difference of direct sunlight is greater than that of scattered light; However, the brightness difference of the incident light of the south-facing door or window is greater than that of the north-facing door or window. When shooting, in order to coordinate the brightness of the shot picture, auxiliary light can be added or scene conditions can be changed appropriately to adjust the brightness difference.

Third, the angle of characters and lighting effects.

The angle between the face of indoor people and the door or window plays a decisive role in the lighting effect of photographic pictures. As long as a person's face moves a little, the light effect of the photo will change. If the figure is in the middle of a door or a foreign country, and the face is facing the door or window, then the light effect of the face is plane light, which can clearly set off the outline of the figure regardless of the background. When a person's face forms a 90-degree angle with the window, that is, when the light shines from the side, the light effect of the face is all-round, and the cheek lines facing the door or window are obvious. A reflector must be used at the same time to reduce the shadow on the backlight side. If the face forms a 45-degree angle with the door, window and window, the light effect of the face is forward metering, which can produce better stereoscopic effect; If you adjust the brightness difference of facial lighting with reflector at the same time, the effect will be better. If people are arranged in front of a window and exposed according to the brightness of the incident light from the window, the effect of silhouette photos can be obtained. If there are too many indoor doors or windows and the light does not meet the requirements, screen windows, curtains and other shielding measures can be adopted to make the light and shade match properly and the light ratio moderate.

Fourth, the mastery of exposure.

When using indoor spotlight to shoot portraits, due to the dim light, there must be enough exposure to make the image density appropriate. When shooting, it is best to use an exposure meter to measure the exposure. In addition, when using indoor spotlight to shoot portraits, it is better to use tripod or chair to fix the camera because of the long exposure time, so as to ensure the best image definition.
