If wedding photography is not satisfied with the studio, where should I go to complain effectively?

From the perspective of contract law, you have signed a contract with the filming unit. According to the contract law, the contractor has the obligation of quality assurance. According to the principles of civil law and the provisions of contract law, you can ask the shooting unit to modify, redo or replace it, and the shooting unit has the obligation to help you modify, redo or replace it.

I suggest you don't complain to the Consumers Association. Consumers association is a non-governmental organization and has no enforcement effect. If no results are obtained after many consultations, you can bring a lawsuit to the court and apply for enforcement if necessary.

In addition, you can also claim compensation for mental damage. As you said, marriage is a woman's lifelong event, and wedding photos have specific commemorative significance. So, you can apply for compensation. Good luck.
