This work shows that the photographic discourse is in close connection with the legal history and ideology. Questions that concern on what an image is, the relationship between photographic image, truth and objectivity, or the power of narrative construction of the image directly concern the concept of Law. Like a photograph, the Modern Law was born with the same zeal for truth and absolute faith in science. Under the veil of neutrality and objectivity, he sought the security and control of human relationships, with the same aspiration to possess, reify and commercialize Nature and Humanity. As it happens with the first photographs, the Modern State and Law managed to approach the truth by basing themselves on the empirical facts as well as on the spiritual ideas, although once the bourgeois narrative discourse was established, with promise of duration and permanence, the moral foundation was forgotten. However, the other facet of photography is subjective and creative, and so is that of Law. Therefore, the Law cannot be neutral. It shows and generates a certain credible ideological discourse about the form of just organization. Speaking of the narrative power of Law shows the legal capacity to invent Justice and, therefore, its ideological dangers and its emancipatory possibilities.
