    3D negative space beyond stereoscopy
    (Edições Universitárias Lusófonas, 2017) Parmeggiani, Paolo; ECATI - School of Communication, Architecture, Arts and Information Technologies
    This paper investigates the relationship between photography, stereoviews and visual icons in Venice, and proposes an experimental video that integrates stereoscopic representations with ambient sounds. The article opens with a historical analysis of the stereoviews made in Venice, highlighting the repertoire of subjects, technology and stylistic choices adopted by the most relevant photographers of the late nineteenth century. The second section proposes an experimental project that attempts to replace the Venetian iconic touristic photographs and stereoviews. The aim is to investigate how to help the viewer focus on depth and negative spaces in a virtual space by walking him/her through different parts of the urban layout. The author discusses which of the main features are adopted to create an immersive experience through a digital combination of stereoscopic photography and binaural ambient sounds. The result indicates that it is possible to capture the essence of the 3D experience of a typical touristic sightseeing tour by applying specific digital transformations to a stereoscopic kinematic flow.

    From the observatory to the classroom : space images in the keystone “600 SET” and “1200 SET”
    (Edições Universitárias Lusófonas, 2017) Pérez Gonzalez, Carmen; ECATI - School of Communication, Architecture, Arts and Information Technologies
    This paper introduces the astronomical images of the Keystone 600 SET and 1200 SET, and the original photographic plates from which they were printed, analysing both the photographic plate and the published card. The astronomer's work will be discussed together with the method of achieving the stereoscopic effect for the different celestial bodies. Of particular interest was the method of taking advantage of the lunar libration for producing Moon stereographs used by British amateur astronomer Warren de la Rue (1815-1889). He was a pioneer who both established and used this method as early as the 1850s. In addition, this study will also explore the method used decades later on by Edward Emerson Barnard (1857-1923), and other astronomers working at the Yerkes Observatory, to produce stereographs of other celestial bodies. Analysis of how Keystone and other companies enabled a democratization of astronomical portraiture will also be performed and can be attributed to the inclusion of astronomical images in their educational set of stereographs, which were used as leading visual tools to help students learn about our earth and its neighbours.
