Jewelry shows are generally not allowed to take pictures. Even if the organizer allows it, the merchant may not allow it. This is the rule. All jewelry, especially jewelry design, is generally not allowed to take pictures.

There are two solutions: 1. You are the media, apply for a media license from the organizer and tell the merchants that I am the cooperative media of the organizer. Of course, you should post a press release to the organizer afterwards. 2, talk to the merchants themselves and talk to others more, but generally don't take pictures without buying.
