How about taking portraits on cloudy days?

First, adjust the white balance, use the existing light source, and add 1~2 flashlights. The choice of scene is very important. Jeans are blue, choose a light background, and the general portrait aperture can be used. Improve some saturation, pay attention to color composition, and the rest is backlight or sidelight. You must fill the light with a flash. You must choose full manual, face spot metering, single focus mode, large aperture, low ISO, and the background should not be too bright.
