What is the purpose of using a crane camera at a wedding?

The advantage of a crane camera is that it is more flexible than a fixed camera, has a wider angle of view, and can obtain more lens effects.

When using a camera crane at a wedding, the main purpose is to shoot a large panoramic lens. Because the occasion is relatively large, it is difficult to shoot all the shots from a fixed camera position. However, the camera crane can take advantage of the arm length to shoot many unique shots. For example: overhead shots, push-and-pull shots, full-field shots, etc.
