The series AURA CORTEX PIXELS NANQUIM is the result of a long practice and reflection on the acts of inscription and limits of the production / reproduction of images in a dialogue between authenticity, originality and reproducibility from the Benjaminian thought. The purpose is to subvert the here and now of the originals, in this case, artworks on images reproduced in books and magazines, photographing them with a camera of cellular and using resources like lights and filters in the elaboration of another image. In this way, it is sought to capture some possibilities immanent to the original ones and resized from their doubles, uprooting the object of art, said commonly equal and / or identical to itself in the materiality of the work, thus disrupting the notion of authenticity from the the constitution of a new image, which I call digital engraving for the time being, based on the idea or principle of reproducibility.
