El santo sudario de Turín podría ser el autorretrato de Leonardo - TopicsExpress

El santo sudario de Turín podría ser el autorretrato de Leonardo da Vinci, realizado por el artista gracias a una “peculiar” técnica de “impresión fotográfica”, según Lillian Schwartz, consultora de la Escuela de Artes Visuales de Nueva York. El artista, para pintar el santo sudario, habría construido la primera cámara oscura de la historia. Da Vinci, según Schwartz, colocó sobre la tela de lino una emulsión fotosensible -clara de huevo con gelatina- en una habitación oscura y sellada. Frente a la tela, en la pared, el artista practicó un agujero en el que colocó una lente de cristal: sobre un pedestal, ante la lente, Da Vinci puso un busto que representa su rostro. Tras días de exposición la imagen de la estatua quedó impresa en la tela.
