This is one part of the material. It comes from pictures that are due to civilization. This is what water does with random pieces of wood that end up on the beach. No one puts these things into signification. The work is only about the fact that one picture material cannot be without the other.
People often see a contradiction here.
These images are reduced to the pure fact of their materiality. So, in a way, it functions like viewing the news on television, without the sound. Sometimes the sound is on and sometimes it isn't. Sometimes you pay attention to the program and sometimes you don't. I don't think that the information has a right order in itself.
