Parallax (memory as a torn page)

Morris, Frank William January 1985 (has links)
The purpose of this creative project was to explore the possibilities of words and photographic images in expressing mood. The particular mood that was to be expressed came from the observation of small rituals. These small rituals are an avenue that humans tend to derive meaning and continuity. Beyond this, the use of the Platinum/ Palladium photographic process as an expressive tool was examined.

No. of bitstreams: 1 Paula Martinelli de Araujo.pdf: 6706920 bytes, checksum: 0fe67b1b3d480a1924fdd581d525c41d (MD5) Previous issue date: 2018-06-18 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / This research has as its starting point the access to the studio and the creation archives of the Brazilian artist Eustáquio Neves. The investigation of the paths identified in Neves' s works, sketches, notes and speeches, seeks to establish relations between the creation processes and the communicating presence materialized in the artist's works, in order to discover how the procedures adopted by the author transform images into manifestos that carry memories deliberately evoked, as they populate a fictional universe within their own times and spaces. Neves places photography in the context of the visual arts by creating complex images in which the process reminiscences - both photographic and extra-photographic - impose themselves, as well as the political statement. Presence therefore results from a semantic investment that permeates the entire creation process and, in the case of Neves, is amplified by the unconventional use of these procedures. The establishment of links between works, author and context of production aims to detect nexuses and recurrences between the material, in its various stages of development, and pertinent questions about contemporary visual arts. The academic treatment is made from the perspective of process criticism in accordance with Cecilia Salles' theoretical contributions and gives rise to discussions about photographic times and spaces, authorship, memory and archives. Alongside Salles are authors who collaborate for an interdisciplinary approach: Vincent Colapietro, Henri Bergson, Edgar Morin, Georges Didi-Huberman, Jacques Rancière and Michel Foucault / Esta pesquisa tem como ponto de partida o acesso ao ateliê e aos arquivos de criação do artista Eustáquio Neves. A investigação dos percursos identificados nas obras, esboços, anotações e falas de Neves busca relações entre os processos de criação e a presença comunicante materializada nos trabalhados do artista, visando descobrir de que maneira os procedimentos adotados pelo autor transformam imagens em estandartes que carregam memórias deliberadamente evocadas enquanto povoam universo ficcional com seus próprios tempos e espaços. Neves coloca a fotografia no contexto das artes visuais ao criar imagens complexas nas quais o clamor político e as marcas do processo – tanto fotográfico quanto extrafotográfico – se impõem. A presença resulta, portanto, de investimento semântico que perpassa todo o processo de criação e, no caso de Neves, é amplificado pelo uso não convencional desses procedimentos. O estabelecimento de vínculos entre obras, autor e contexto de produção tem como objetivo detectar nexos e recorrências entre os trabalhos de Neves, em suas diversas etapas de desenvolvimento, e questões pertinentes acerca das artes visuais contemporâneas. O tratamento acadêmico do material, feito sob a perspectiva da crítica de processos de acordo com contribuições teóricas de Cecilia Almeida Salles, faz emergir discussões sobre os tempos e espaços fotográficos, autoria, memória e arquivos. Ao lado de Salles aparecem autores que colaboram para uma abordagem interdisciplinar: Vincent Colapietro, Henri Bergson, Edgar Morin, Georges Didi-Huberman, Jacques Rancière e Michel Foucault

Câmera e pincel : grafismos corporais e processos fotográficos /

Fonseca, Amanda Ferreira Branco da. January 2017 (has links)
Orientador(a): Agnus Valente / Banca: Milton Terumitsu Sogabe / Banca: Andréa Brächer / Resumo: A presente dissertação aborda minha produção no campo da fotografia expandida, em ensaios que unem pintura corporal e processos fotográficos históricos. Também inclui o desenvolvimento da série Religare, que é o corpus resultante dessa pesquisa de mestrado. Trata-se de um ensaio realizado com a própria artista como modelo da pintura corporal, e revelado com a técnica goma bicromatada sobre madeira, em grandes dimensões (algumas medindo cerca de 88 x 150 cm). Tanto no caso dos ensaios anteriores a essa dissertação, quanto em Religare, os processos são marcados por experimentação e desenvolvimento de técnicas, em geral híbridas, envolvendo: desenho manual dos grafismos corporais, captação digital das imagens, processamento digital, impressão em transparências e revelação das imagens usando processos fotográficos artesanais (marrom Van Dyck, cianotipia e goma bicromatada). Buscando referências na prática da pintura corporal realizada por diversas etnias indígenas, e em posturas do Yoga, esses ensaios desenvolvem uma poética de resgate da vivência do Sagrado, que parece distante na vida urbana contemporânea. O corpo é o instrumento para isso, é o estar aqui e agora. Nos ensaios apresentados, o corpo ganha destaque, conferido pela pintura corporal, pela referência a posturas de Yoga, e pelo trabalho artesanal, também presente na pintura corporal e nos processos fotográficos. Também há destaque para o "corpo" da fotografia, a materialidade do meio, tendo como suportes o papel, o tecido e a madeira / Abstract: The present dissertation approaches my production in expanded photography, in photographic essays that unite body painting and early photographic processes. It also includes the development of Religare, essay that is this master's research resulting corpus. The artist herself is model for body painting, and the images are printed in large sizes (some about 88 x 150 cm) using gum bichromate on wood. In previous essays, as in Religare, the processes are based on technical experiment and development, which are usually hybrids, including: handmade drawing of body painting, digital capture of images, digital processing, digital negatives printing and photography printing using early photographic processes (Van Dyck brown, cyanotype and gum bichromate). Seeking references in the indigenous practice of body painting and Yoga poses, those essays develop a Sacred experience rescue poetics, due to this experience seeming distant from contemporaneous urban life. The body is the instrument for this experience, it's "being here and now". At the presented essays, the body is highlighted by the body painting, the reference to yoga poses, and by handcraft process, which includes body painting and early photographic processes. Also the photography "body" is highlighted, the media materiality, embodied by paper, fabric and wood / Mestre

Perceptual content and tone adaptation for HDR display technologies / Adaptation perceptuelle du contenu et des tons pour les technologies d'affichage HDR

Abebe, Mekides Assefa 07 October 2016 (has links)
Les technologies de capture et d'affichage d'images ont fait un grand pas durant la dernière décennie en termes de capacités de reproduction de la couleur, de gamme de dynamique et de détails des scènes réelles. Les caméras et les écrans à large gamme de dynamique (HDR: high dynamic range) sont d'ores et déjà disponibles, offrant ainsi plus de flexibilité pour les créateurs de contenus afin de produire des scènes plus réalistes.Dans le même temps, à cause des limitations des appareils conventionnels, il existe un gap important en terme de reproduction de contenu et d'apparence colorée entre les deux technologies. Cela a accentué le besoin pour des algorithmes prenant en compte ces considérations et assurant aux créateurs de contenus une reproduction cross-média fidèle.Dans cette thèse, nous focalisons sur l'adaptation et la reproduction des contenus à gamme de dynamique standard sur des dispositifs HDR. Tout d'abord, les modèles d'apparence colorée ainsi que les opérateurs de mappage tonal inverse ont été étudiés subjectivement quant à leur fidélité couleur lors de l'expansion de contenus antérieurs. Par la suite, les attributs perceptuels de clarté, chroma et saturation ont été analysés pour des stimuli émissifs ayant des niveaux de luminance de plus hautes gammes et ce en menant une étude psychophysique basée sur la méthode de mise à l'échelle de partitions. Les résultats expérimentaux ont permis de mener à la définition d'un nouvel espace couleur HDR efficace et précis, optimisé pour les applications d'adaptation de la gamme de dynamique. Enfin, dans l'optique de récupérer les détails perdus lors de captures d'images standard et d'améliorer la qualité perçue du contenu antérieur avant d'être visualisé sur un dispositif HDR, deux approches de correction des zones surexposées ou ayant subi un écrêtage couleur ont été proposées. Les modèles et algorithmes proposés ont été évalués en comparaison avec une vérité terrain HDR, menant à la conclusion que les résultats obtenus sont plus proches des scènes réelles que les autres approches de la littérature. / Camera and display technologies have greatly advanced in their capacities of reproducing color, dynamic range and details of real scenes in recent years. New and powerful high dynamic range (HDR) camera and display technologies are currently available in the market and, recently, these new HDR technologies offer higher flexibility to content creators, allowing them to produce a more precise representation of real world scenes.At the same time, limitations of conventional camera and display technologies mean that there is a significant gap in terms of content and color appearance reproduction between new and existing technologies. These mismatches lead to an increased demand for appearance studies and algorithms which take such under consideration and help content creators to perform accurate cross-media reproductions.In this thesis we mainly considered the adaptation and reproduction of standard dynamic range content towards HDR displays. First, existing color appearance models and reverse tone mapping operators were subjectively studied for their color fidelity during dynamic range expansion of legacy contents. Then perceptual lightness, chroma and saturation attributes were analyzed for emissive stimuli with higher range of luminance levels using adapted psycho-visual experimental setups based on the partition scaling method. The experimental results lead to a new, more efficient and accurate HDR color space, specifically optimized for dynamic range adaptation applications. Finally, to recover lost details and enhance the visual quality of legacy content before visualizing on an HDR display, two methods for color-clipping and over-exposure correction were introduced. The models and algorithms presented, were evaluated relative to HDR ground truth content, showing that our results are closer to the real scene than can be achieved with previous methods.
