Portraits publics, portraits privés 1770-1830
Fran?ois Brunet
Transatlantica : Revue d'études Américaines , 2007,
Abstract: Quoique très francocentrique pour une exposition co-produite par la Royal Academy et le Guggenheim Museum, cette galerie de portraits de l’époque romantique justifie une notule dans une revue américaniste pour trois ou quatre raisons. On peut y voir, dans la première salle, l’un des grandiloquents portraits en pied de George Washington par Gilbert Stuart (pas le Landsdowne mais une version proche) voisiner avec un Napoléon de David et un autre d’Ingres, et mesurer par cette juxtaposition ino...
Zur Interpretation fotografischer Portr ts: Autobiografie, Zeitperspektiven und zwei Schulfotografien Interpreting Photographic Portraits: Autobiography, Time Perspectives, and Two School Photographs Interpretación de retratos fotográficos: Autobiografía, perspectivas de tiempo y dos fotografías escolares

Forum : Qualitative Social Research , 2011,
Abstract: Dieser Beitrag versteht sich als Begleitartikel zu der allgemeinen Diskussion in "Fotografische Portr ts: Narration und Ged chtnis" (ROBERTS 2011). Ich versuche mit dem Folgenden zu der gegenw rtigen Auseinandersetzung mit visuellem Material beizutragen, indem ich einen spezifischen interpretativen Ansatz zu fotografischen Portr ts verfolge, n mlich zu Selbstportr ts, Bildern also, die wir selbst oder andere von uns gemacht haben, allein oder in einer Gruppe, informell durch Verwandte/Bekannte oder professionell durch Fotostudios. Ich nutze hierbei einen (auto-) biografischen Fokus und frage, wie wir solche Selbstportr ts betrachten und sie mit Erinnerungen, aktuellen Erfahrungen und Vorstellungen von Zukunft verknüpfen. Als Beispiele verwende ich zwei Schulfotografien von 1956/1958, als ich sechs bzw. acht Jahre alt war, und unterziehe sie einer Analyse, die "Zeitperspektiven" und einige verwandte Konzepte beleuchtet. Ich bediene mich in diesem Zusammenhang zweier Narrative: erstens der Kommentierung der beiden Fotografien vor dem Hintergrund meiner kindlichen Entwicklung (z.B. k rperlich, intellektuell) im Alter von sechs bzw. acht Jahren, und zweitens mit Blick auf mein gegenw rtiges Aussehen und meine gegenw rtigen Aktivit ten, die ich mit den Erinnerungen zu verbinden versuche, die durch die Fotografien ausgel st werden. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1102252 This article is a "companion" piece to a more general discussion in the preceding article, Brian ROBERTS' (2011) "Photographic Portraits: Narrative and Memory". Here the attempt is to enhance current attention to visual materials by exploring a particular interpretive approach to the photographic portrait—self-image—images taken of us by ourselves or taken by others (portraits taken by friends or relatives, or by professionals), alone or as part of a group. The article is autobiographical in focus; it explores how we "look" at personal photographs and associate them with memories of our past, our current experience, and the future. It uses as examples two school photographs taken in 1956-8 of me (the author) aged six to eight years old and applies a form of analysis employing "time perspectives" and a range of associated concepts. Two narratives are given: first, a commentary on the two school photographs and my childhood development (e.g. physical, intellectual) between six to eight years old, and second, my current outlook and activities and how they connect with the memories raised by the photographs.

Computer Science , 2015,
Abstract: Digital portrait photographs are everywhere, and while the number of face pictures keeps growing, not much work has been done to on automatic portrait beauty assessment. In this paper, we design a specific framework to automatically evaluate the beauty of digital portraits. To this end, we procure a large dataset of face images annotated not only with aesthetic scores but also with information about the traits of the subject portrayed. We design a set of visual features based on portrait photography literature, and extensively analyze their relation with portrait beauty, exposing interesting findings about what makes a portrait beautiful. We find that the beauty of a portrait is linked to its artistic value, and independent from age, race and gender of the subject. We also show that a classifier trained with our features to separate beautiful portraits from non-beautiful portraits outperforms generic aesthetic classifiers.
Photographs in Autobiographies: Identities in Progress
Fabien Arribert-Narce
Skepsi , 2008,
Abstract: This paper will deal with the use of photographs in several French contemporary autobiographies (Roland Barthes, Annie Ernaux, Denis Roche, Hervé Guibert, Marguerite Duras). My aim will be to present this corpus of works grafting photographs onto various kinds of texts, works that can be called photobiographies. In the second part, I will analyse several issues raised by this new literary field. In particular I will explain why the use of photographs changes the forms and the conditions of the autobiographical expression. Indeed, photographs problematize the representation and the construction of personal identities.
Digital publics and participatory education  [PDF]

Digital Culture & Education , 2010,
Abstract: This article—a collaborative exploration between instructors, students, and members of the broader, digital classroom community—explores how the strategic incorporation of sociotechnical networks and digital technologies facilitates literate practices that extend the classroom in productive ways. The article builds toward coauthors’ reflective practices (Sch n, 1983), or “participatory perspectives”, had during an undergraduate English Studies course at a mid-sized, public, American university. Specifically, participants argue that these literate practices afforded not just information sharing, but the opening up of a traditional classroom to include broader digital publics and collaborative knowledge work (Spinuzzi, 2006). Toward this end, we ground literate practice in scholarship that attends to public writing in online spaces, and theoretically frame our argument using Jenkins et al.’s (2006) principles of participatory education. We then detail the specific curricular approach deliberately designed to create digitally connected publics and end with generalizable significance of coauthors’ participatory perspectives.
On the exposure of hemispherical photographs in forests  [cached]
Becksch?fer P,Seidel D,Kleinn C,Xu J
iForest : Biogeosciences and Forestry , 2013, DOI: 10.3832/ifor0957-006
Abstract: At least 10 different methods to determine exposure for hemispherical photographs were used by scientists in the last two decades, severely hampering comparability among studies. Here, an overview of the applied methods is reported. For the standardization of photographic exposure, a time-consuming reference measurement in the open land towards the unobstructed sky was required so far. The two Histogram Methods proposed here make use of the technical advances of digital cameras which enable users to assess a photograph’s histogram directly at the location of measurement. This avoids errors occurring due to variations in sky lighting happening in the time span between taking the reference measurement and reaching the sample location within the forest. The Histogram Methods speed up and simplify taking hemispherical photographs, and introduce an objectively applicable, standardized approach. We highlight the importance of correct exposure by quantifying the overestimation of gap fraction resulting from auto-exposed photographs under a wide range of canopy openness situations. In our study, gap fraction derived from auto-exposed photographs reached values up to 900% higher than those derived from non-overexposed photographs. By investigating the size of the largest gap per photograph and the number of small gaps (gaps contributing less than 0.1% to gap fraction), we concluded that the overestimation of gap fraction resulted mainly from the overexposure of vegetation surrounding large gaps.
The publics and the government of life in social networks
Saulo Mota
Verso e Reverso , 2012,
Abstract: The goal of this study is an analysis of the relationship between the publics, analyzed by Gabriel Tarde and the government of practices of life, studied by Michel Foucault in the context of social networks, making a comparison between the practices of this kind of social grouping in the early twentieth century with its update in the social networks context in the twenty-first century. Initially we investigate the relationship between a private company with its public, identifying the salient elements of the first moments of this type of social grouping. Then the practices of control of life are identified in the context of the early twentieth century and then their transformation in the context of the social networks. The conclusion points out how the publics have become components of the government of life in the context of social networks in their articulation with contemporary neoliberalism.
People Portraits and Cartoon Algorithm Study  [cached]
Weihua Gai,Dakun Zhang
Computer and Information Science , 2009, DOI: 10.5539/cis.v2n1p195
Abstract: This paper is to use the positive face to automatically generate a photo realist style, or has the effect of exaggerated cartoons. It includes two aspects: First, face the portrait photos automatically into production; Second, face deformed to generate cartoon effect. AAM model is a statistical model, can be well applied to the facial characteristics of location. In this paper, by improving the traditional AAM ways to overcome its lack of color information processing, design a more effective figure portraits Generation System. Then, take the initiative to shape a model feature extraction and characteristics of the method of combining the human face of the main features of automatic deformation, the cartoon characters generated portrait.
Building Meaning in Digitized Photographs  [cached]
Paul Conway
Journal of the Chicago Colloquium on Digital Humanities and Computer Science , 2009,
Abstract: This paper explores how visual meaning is built through the transformation of photographic images from analog (prints or negatives) to digital bitmaps. The paper frames the issue of digitization of photographs and their use in digital humanities scholarship within varying theoretical perspectives on visual representation. The paper incorporates a model that describes how digitization procedures (guidelines and best practices) express the intentions of the digitizer. It illustrates the mechanisms at play in digital collection building, particularly the extent to which technical decisions regarding image quality affect the digital representations of original photographic resources in ways that may be detectable and important to digital humanities scholars. The paper concludes with implications for digital humanities scholarship of using general-purpose Image Digital Archives.
