What are the good ways to take portraits in rainy days?

Look for places where there is a lot of sunlight indoors, such as windows or cafes or restaurants with floor-to-ceiling glass. There are two biggest advantages to choosing these places. First, the light passing through a window or floor-to-ceiling glass will change from top to bottom to horizontal light from left to right or from right to left. Horizontal light is very suitable for portrait shooting, and the brightness and darkness of the face will become very natural and comfortable.
