1, it is illegal not to distribute negatives. It is illegal for a guest to take photos in a photo studio without sending negatives. Whether it is a wedding photo or the original negative, the studio should deliver it to consumers unconditionally. For negatives, the photo studio can't keep them without the customer's consent. It should be given to the customer without additional film fees.

2. Legal basis: Article 17 of the Copyright Law.

The ownership of copyright shall be stipulated by the client and the trustee through the contract. If the contract is not clearly stipulated or concluded, the copyright belongs to the trustee.

Second, does buying another photographic film in the studio infringe on the right to portrait?

Buying another photographic film in the studio is not an infringement of the right to portrait, but an infringement of the right to know. Wedding audio-visual products produced by wedding companies, including photos, videos, CDs, etc. , should guarantee the quality and deliver it to the customer within the specified time, and all the original materials in the recording process should be handed over together. It provides a basic guarantee for many newcomers who are about to take wedding photos. As a photo studio, we should standardize our own business behavior, achieve orderly operation, and have rules to follow, so as to effectively protect the rights and interests of customers. At present, wedding photos or artistic photos are taken in the studio, and the negative of the photos is not given. If the consumer wants to get the film back, the studio will charge the consumer different fees for each film. This phenomenon is relatively common in the studio at present.
