Can taking wedding photos on cloudy days have a bad effect?

It's really better to take wedding photos on sunny days, but it's hot on sunny days and it's easy to burn makeup.

Taking pictures is a professional thing. Your wedding photos should have a keynote, if the keynote is set. It is not necessarily sunny.

After taking photos, the photographer will also do retouching and editing. In this process, if the light is not enough, it can also be polished.

Taking wedding photos on the spot will also be taken with lighting tools, and there will also be lighting effects. But it's definitely not as bright as the big sun.

To sum up, you can shoot on cloudy days, and the effect will definitely be worse than that on sunny days. But it won't have much impact. It is recommended to follow the professional advice of the photographer.
