Would it be bad to get married without a photographer?

It depends on your preference and that of your lover. Some people want a souvenir, which is good. I suggest that it is better to invite one. After all, marriage is a once-in-a-lifetime event, a major event in life. I will keep it at home in the future, which is both a memoir and a souvenir of my youth. It's no big problem not to invite me.
