Would it be bad not to hire a photographer during the wedding party?

This depends on the preferences of you and your lover. If you want a souvenir, it is still good. I recommend hiring a good one. After all, getting married is a once-in-a-lifetime event and a major event in life. Keeping it at home will not only be a memoir, but also a souvenir of your youth. If you don’t ask, it’s not a big problem
