Photography is in a room with poor light. How to adjust the picture if it is not bright?

If the photographic light is insufficient, you can choose a light supplement device.

Whether indoor portrait or outdoor portrait, in the case of insufficient light, lighting equipment is preferred. When the light is insufficient, you can also increase the exposure by adjusting the camera parameters. When shooting portraits, we must first ensure the accurate exposure of human faces, and then do a good job in metering. Then we might as well choose spot metering. Spot metering mode is about 3% of the area in the measurement picture. When shooting portraits, the metering mode is changed to spot metering, and then the face is accurately measured to ensure the accurate exposure of the face.
