Lux in Tenebris: un flujo de trabajo para digitalizar y visualizar obras de arte pictóricas en contextos museísticos complejos



Palabras clave:

museos, fotografía, renderizado en tiempo real, eliminación de sombras, Fra Angelico


En el ámbito museístico es frecuente encontrarse con limitaciones logísticas que dificultan la documentación de las obras de arte. El patrimonio pictórico presenta además otras criticidades debidas a la imposibilidad de modificar la iluminación: basada en criterios de conservación y comunicación, haciendo resaltar las características materiales, cromáticas y de ejecución. Esto conduce a situaciones inadecuadas para el levantamientos por imágenes fotográficas, ya complicadas en sí por las complejas propiedades ópticas de los materiales. La técnica que aquí se presenta fue desarrollada para la documentación de la Anunciación (1430-32) de Fra Giovanni Angelico (Museo de la Basílica S. Maria delle Grazie, San Giovanni Valdarno, Arezzo) y permite eliminar y atenuar fenómenos indeseables debidos a las condiciones específicas del contexto museístico. Se mostrará una estrategia capaz de eliminar las sombras nitidas, así como los fenómenos de claroscuro, de las texturas asociadas al modelo digital de la pintura y su marco, garantizando su fidelidad visual.
