    3-D: Realist Illusion or Perception Confusion? : The Technological Image as a Space for Play
    (Edições Universitárias Lusófonas, 2021) Gunning, Tom; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    This paper seeks to explore the ambiguities of the devices of stereoscopic imagery both moving and still. Since the invention of the stereoscope there has been the claim that stereoscopic images gave a more complete representation of their objects by adding an appearance of three-dimensionality. However, it has also been acknowledged that stereoscopy creates merely an optical illusion of three-dimensionality, one which presents its own perceptual ambiguities. Moving from the issues raised by Jonathan Crary in his discussion of stereoscopy in The Techniques of the Observer to the history 3-D films, this paper explores how the tension between an illusionist approach of fooling the senses into believing an image and an outright challenge to representation which fosters the contradictions of stereoscopic images has made 3-D a dynamic aesthetic form. I will discuss both commercial films, such as the late Transformers series, as well as avant-garde works by Ken Jacob and The OpenEnded Group (Marc Downie and Paul Kaiser).

    Gabriel Lippmann (1845–1921) & Frederick Ives (1856–1937) : The French Physicist Versus The American Inventor in the Pursuit of Colour and 3-Dimensionality
    (Edições Universitárias Lusófonas, 2021) Gamble, Susan; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    I explore the reception to photographic invention at the end of the nineteenth century and how photographic practice was embraced by the Academy with Lippmann’s Nobel Prize-winning process. Whereas Lippmann published a theory in the public domain, a requirement for the Nobel Prize, Ives was dependent on commercial sales. However, Ives was a critic of Lippmann’s process which competed with his own efforts for display and publicity. Here, I review the division of theory with mechanical invention that existed between Lippmann’s and Ives’ 3-Dimensional concepts. And I discuss the assessment by Herbert Ives (1882–1953), the son of Frederick Ives, of both these inventions.

    Media Archaeology as Film Practice : The Werner Nekes Collection
    (Edições Universitárias Lusófonas, 2021) Monteiro, Helena Gouveia; Escola de Comunicação, Arquitetura, Artes e Tecnologias da Informação
    The Nekes Collection of visual techniques and optical devices is an invaluable resource for scholars and filmmakers researching a wider history of film and animation comprised of early and pre cinematographic materials.Items relating to three-dimensional optical techniques such as stereoscopes, perspective theatres, peepshows, vues d’optique, and zograscopes (the bulk dating from the mid-18th century to the early 20th century) make for a significant part of the collection and reveal an interest in three-dimensional representation and binocular superimposition.The films of Dore O. (b.1946) and Werner Nekes (1944–2017) stand out in terms of the richness of experimental visual techniques in dialogue with this extensive historical archive used primarily as a source for creating new films and devising new ways of engaging with the medium.This paper presents an overview of the collection and investigates the connections between the objects found in the archive and Nekes and O.’s editing techniques, with a particular focus on three-dimensionality and spatial illusions created through transparency and dissolving effects.
