Seek digital camera shooting skills! For example, how to shoot portraits, shoot on cloudy days to reduce noise, and shoot portraits on sunny days is too dark and overexposed.

You may be talking about shooting against the light, so the background is either overexposed or the portrait is a little dark. In this case, manual exposure and forced flashing can be used. People should stand in the effective range of the flash, not only the background will not be too violent, but also the portrait will have unexpected effects. In the absence of other light sources, only using the aperture shutter will not have a good effect unless you need such an effect (as long as the outline).
