Introduction of reflected light

The light reflected by an object is called reflected light. Using indirect light distribution in photography has the same effect as astigmatism lighting. Because of the frequent flashing lights, it is often used in indoor photography, and people call this method reflected flash. To this end, there are reflective umbrellas. When the umbrella reflector is not used, the light shines on the bright wall or roof behind the camera. The brightness will drop below 1/4, and there will be no eye-catching shadows, which will make the photo not like a lamp. The decrease in brightness can be compensated by high-sensitivity film.
