Is there a charge for wedding photos? National regulations are free, but why charge?

There should be no extra charge. Took nearly 200 wedding photos, and then gave all the negatives when choosing photos. I think I have to make an agreement with the store before signing the agreement and ask you to give me all the negatives. Otherwise, when you give money, they will kill it ... so it's better to sign an agreement with the store. Don't believe what they say verbally. A friend of mine is choosing because he didn't sign any agreement before. Everyone thinks it's beautiful. I spent 30 yuan to buy 30 photos. I feel distressed ... I regret it. I hope I can help you and wish the landlord happiness. . .
