Who should pay for the wedding photos?

the money for wedding photos is supposed to be paid by the man. However, the actual situation is sometimes different, such as:

1. There is not much money for wedding photos. Generally, if you have money, you will pay it, because parents need to pay a lot of money and don't care about these thousands.

2. The woman has money, and she doesn't care who pays. Maybe she swipes her card directly when she pays at the scene. So there's no hero rule.

3. It is understandable that the boyfriend's parents can pay for the child if he has no money.
