What does the photographer's funeral have to do with it?

The photographer has nothing to do with the undertaker.

Photographers are professionals who create works of art by taking photos and post-production. Funerals are professionals who sort out the bodies of the dead and restore them to the most natural state.

However, in some literary and artistic works, photographers and undertakers may be set as occupations with some connection. For example, they all deal with the "past" and have awe and respect for life. This setting may be due to the need of creation, putting these two occupations together and highlighting the theme or emotional color of the work. But this does not mean that there is any direct or indirect relationship between photographers and undertakers in real life.
