Should I send all the negatives?

Legal analysis: there is no explicit provision on whether a photo studio takes pictures. You need to ask or negotiate in advance, and the price may vary depending on whether you shoot or not. Because the negative is the result of the photographer's labor, the studio often takes a lot of unnecessary photos. The photos that the average customer has not selected will not be given to the studio because they are not included in the shooting price. So the studio can't give all the negatives.

Legal basis: Civil Code of People's Republic of China (PRC).

Article 502 A lawfully formed contract shall become effective upon its formation, unless otherwise provided by law or agreed by the parties.

In accordance with the provisions of laws and administrative regulations, if the contract should go through the approval procedures, such provisions shall prevail. If the failure to go through the formalities such as approval affects the effectiveness of the contract, it will not affect the performance of the obligation clauses such as approval and the effectiveness of relevant clauses in the contract. If the party that should go through the formalities for approval fails to perform its obligations, the other party may require it to bear the responsibility for violating its obligations.

The modification, assignment and dissolution of a contract shall be subject to the provisions of laws and administrative regulations, and the provisions of the preceding paragraph shall apply and shall be subject to approval.

Article 503 Where an unauthorized agent enters into a contract in the name of the principal, and the principal has started to perform the contractual obligations or accepted the performance of the other party, it shall be deemed as ratification of the contract.
