Abstract

In this interdisciplinary research, the scientific knowledge of optics and the propagation of light in space has been recovered, to generate a sequence of images that can be applied in different ways in pieces of an audiovisual, scenic, sculptural, immersive or digital. The idea of retaking photography, specifically a portrait, meets a proposal that raises the possibility of achieving the reconfiguration of a photographic image with the use of tools directly related to it, such as optical systems and light. The theoretical and experimental formula has its foundations in the study and application of the method known as null screens, which in the field of physics are used to evaluate optical aberrations, in this work we have used this method to work with a photographic portrait, originally made in grayscale. In order to achieve new visualization narratives with the implementation of optics and light, in this case RGB (red, green, blue).

Author Biographies

Edith Vazquez, Universidad Nacional Autónoma de México

Doctor of Arts and Design with the thesis Optical applied to art: a methodological proposal, by the Faculty of Arts and Design, UNAM. I am currently doing a Postdoctoral research stay in the same instance, in collaboration with Researchers from the Institute of Physics and the Institute of Applied Sciences and Technologies, UNAM. I have done research stays for a master's and doctorate at the Università degli Studi del Piemonte, Italy; La Salpêtrière, Paris, France; Universidad del Valle, Cali, Colombia; at the Schule für Fotografie in Berlin, Germany. In an innovative way in the art, I apply the design of optical systems for the formation of images and the method called Null screens by refraction for the mathematical analysis of photographic images and other patterns, with which I propose display variants of the same image. I am part of the groups: Quantum Optics Research, from the Universidad del Valle de Cali, Colombia; Optical tests and optical metrology, from the Institute of Applied Sciences and Technology (ICAT, UNAM). I have some academic publications where I expose my current working method. I have lived and exhibited in Italy, France, Germany, Colombia and Mexico. I have been a speaker at national and international seminars, both on optics and art.

Gerardo García Luna, Universidad Nacional Autónoma de México

Doctor of Fine Arts from the Polytechnic University of Valencia, master of Visual Arts with orientation in Urban Art and graduate in Graphic Design from ENAP (now FAD). He is currently director of the Faculty of Arts and Design, FAD, UNAM. He has a teaching seniority of 25 years, has directed 36 undergraduate and 18 postgraduate theses, and has coordinated activities around one of the main lines of research in his specialty: the link between visual arts and performing art - in a context of interdisciplinary assessment - to generate theatrical performances and public installations. He is the co-author of five books and the author of seven essays and 13 popular articles; He has given 23 conferences in national and international forums, and since 2013 he is a member of the subcommittee for the selection of postgraduate applicants at the FAD.

Gabriel Castillo Santiago, Institute of Applied Sciences and Technology (ICAT-UNAM)

Electronics and Communications Engineer, attached to the Institute of Applied Sciences and Technology (ICAT-UNAM) where he is currently doing a Postdoctoral research stay. He implemented a new analytical method for the design of aspherical lenses reducing their spherical aberration using the caustic equation, as well as an experimental test of the same. He improved this experimental technique during the Doctorate program in Electrical Engineering at ICAT-UNAM, where he specialized in optical tests within the caustic region. He has also collaborated in the development and implementation of research projects. As a result of this collaborative work, he has attended as an author and lecturer in national and international conferences. He has received several grants and support to carry out his research and published academic articles. Interested in the interdisciplinary collaboration processes between art and science, together with Dr. in arts and design Edith Vázquez, with whom he has innovatively implemented the null-screen method for the generation of images and its application in art. He collaborates with other optics students at ICAT, for the organization of scientific dissemination events inside and outside the UNAM.
