The innovation of mechanical reproduction is needed in order to change and improve art. As mechanical reproduction advances, it creates new techniques of art that can be reproducible. However, it poses the question of the authenticity of the artwork. Many can argue that the authenticity of the artwork is diminished when it is reproduced. However, I agree with Benjamin. People do have different perceptions and this can add to the authenticity of the art because the way they perceive it, is also authentic. Additionally, this is also true for the aura of the art. Your understanding of it brings you closer to it.
For example, film. Both the actor and the camera are telling the audience a story. The actor does this by performing on stage while the camera does this by changing angles, close-ups, slow motion, etc. The mechanical reproduction in film is the camera because it does not only capture the scene but it also becomes an extension of the audience. The camera movements put the audience in the film. I disagree that the actors lose their aura with the audience.
I am confused about the two concepts of Dadaism and Fascism. I do not understand how they connect fully to mechanical reproduction. I do understand that fascism believes that war moves the innovation of technology.
