Full textThe problem which underlies this research can be posed as a question: in what ways do the intimacies of bodies harbour politically challenging questions to photography? The answer to this question resides within the aesthetics of the Erotic. The Erotic yields imaginary representations of the origin and its generations. The structure of the fantasy of the subject - through social amplification, scientific discovery, the pluralizing of sexuality and its photographic creations - is in mutation. The visibility of those once marginalized and regarded as "other" signifies a new axis constituting the object of desire. What the "other" produces, then, are his mythologies. The designation of the term "others" implies a boundary of normality and of the homogeneity of the mass. Beyond this point, the physical and psychic territories are to be colonised. The power of the bodies upon themselves, and the power of the bodies despite themselves, underlines the political character of the image. As pictures or advertisements, photography’s taken between the American and the European continents reveal the sexual identity of the Nations. Thus, from the system of binary opposition between the sexes in the twentieth century, we go to the distinctions of genders - queerness - in the twenty-first century. The body and its photographic representations open a new realm of gender, which, at the rhythm of the tempo of a caress, leads to a veritable revolution of the views
Liao, Hui-Ying. "Analyse sémiologique des premières applications photographiques à la médecine." Paris 5, 2006. http://www.theses.fr/2006PA05H024.
Full textIn inquiring into the relationship of the dispositif of photography to the interpretation and the signification of its image, this dissertation elaborates a semiological analysis of the first photographic applications tomedicine, in particular those of Charcot and other researchers (Duchenne). In analyzing those applications which illustrate marvelously the characteristics of the photographic representation, it is necessary to take into consideration the nature and the relation of the components of the dispositif : from the camera and the photographic act to the image obtained and its interpretation. Such a consideration permits the possibility to clarify the ambivalent characteristic of the photographic dispositif, of which the first photographs for medical use are the best examples. The analysis of these images shows that, contrary to the appearance, and to the medical discourse held at that time, the signification of the photographic image is not at all transparent. It is in a close relation with the dispositif and wich the iconic culture that precedet it

Full textThis thesis deals with the problems of automatic localization and recognition of urban objects in high-definition aerial images. Urban object detection is a challenging problem because they vary in appearance, color and size. Moreover, there are many urban objects which can be very close to each other in an image. The localization and the automatic recognition of different urban objects, considering these characteristics, are very difficult to detect and classical image processing algorithms do not lead to good performances. We propose then to use the supervised learning approach. In a first time, we have built a Support Vector Machine (SVM) network to merge different resolutions in an efficient way. However, this method highly increases the computational cost. We then proposed to use an “activation path” which reduces the complexity without any loss of efficiency. This path activates sequentially the network and stops the exploration when an urban object has a high probability of detection. In the case of localizations based on a feature extraction step followed by a classification step, this may reduce by a factor 5 the computational cost. Thereafter, we show that we can combine an SVM network with feature maps which have been extracted by a Convolutional Neural Network. Such an architecture associated with the activation path increased the performance by 8% on our database while giving a theoretical reduction of the computational costs up to 97%. We implemented all these new methods in order to be integrated in the software framework of Berger-Levrault company, to improve land registry for local communities

Full textThe photographic work of Sebastião Salgado focuses on the living conditions of people affected by social distress resulting from civil wars, exploitation, and misery. The pictures are characterised by the quality of their aesthetic composition but they are not primarily works of art. They are rather documentary pictures that represent a social denunciation of intolerable living conditions. Some social scientists specialised in photo interpretation think that his pictures still exhibit too many characteristics of art work and might therefore deform reality. However, others are convinced that just this aesthetic approach constitute its particular strength in sociopolitical communication. The contrasting views reflect the old debate on the relation between politics and aesthetics recently revived by the discussion on the socio-political role of the media in the presentation of social distress. This thesis is based on a representative sample of articles published in print media in which arguments for and against the photographic approach of Salgado are presented. The analytic comparison of the opposed arguments allows an evaluation of the related theoretical concepts. It also reveals an a priori basis of the related ethics, aesthetics, sociology, and politics indicating whether the denouncing character of Salgado pictures is representing an adequate approach to communicate the misery of the world

Full textCirca 1900, new kinds of photographs appear that use screens to give the illusion of depth or of animation. The first section of this dissertation discusses the invention and the theoretical sources of these new processes and their uses up until 1950 (for portraits, in particular). The analysis of this era reveals a fascination for the advance of photographic innovation towards the imitation of human perception of the natural world. The second section studies the commercialization of screen photography after 1950. Innovative physical forms were invented in order to allow new, more widespread uses of the processes (key chains, postcards, amateur photography, etc. ). Screens were used to create intriguing illusions, often simplified with respect to the past and not as naturalistic. The commercial forms of such imagery (physical presentation, uses, aesthetics) are analyzed to understand the meaning of screen photography for the public of different periods

Full textThe main approach of this PhD is to focus on the visual project within Albert Kahn’s work and to broaden the scope by studying what will become of the films from the Archives of the Planet. To achieve this goal, the thesis draws on the whole administrative archives of the Albert Kahn Museum, on the archives of Albert Kahn and his numerous relatives, on the departmental and national archives and through investigations conducted in the archives of the INA (the National Institute for Audio-visual Media), art centres and the film’s archives. By first looking at the kahnian figure through the construction of Kahn’s contemporary and posthumous speeches, the thesis then takes a turn towards an analysis of the kahnian visual project. As it draws on thinkers contemporary to Kahn and on some of his writings, this second part attempts to grasp how the Archives of the Planet have been made possible and how they are embedded in a thinking, both global and specific, on images. Finally, the third part of this work first delves into the period when the films of the Archives of the Planet were “made available” from Albert Kahn’s death to the early 2000s, by drawing on the history of the museal institution and its satellites – such as the “Cinémathèque de Boulogne.” The third part then opens up the reflection by focusing on the futures of the Archives of the Planet and, by studying cases of appropriation of the kahnian films in external productions (Chris Marker, Abel Gance, Nicole Vedrès, Frédéric Rossif etc.) and on television

Full textThis work is an analysis of the methodologies of scientific imagery from photography. I choose to focus on the works of Etienne Jules Marey on chronophotography, on those of G. Haret, A. Dariaux, Jean Quenu and of Jean Quenu, Michel Sempé and Carlos Pavia on radiology, on those of Henri Becquerel on radioactivity discovered by him by using photographie technology, and also on contemporary research in the nanosciences. Methodologies are both methods of visualization and methods of producing images, which enables us to see what is invisible. Movement becomes visible with chonophotography, so do inner-parts of the human body thanks to radiology. Uranic rays can be detected and atoms can be visualized and organized using scanning tunneling microscope. This work also deals with the progress of techniques which made visible in the twentieth century what was invisible before, and gave researchers concrete tools to successfully develop quantum mechanic theory. Scientific imagery also gave researchers concrete tools to verify classical mechanic theories. Scientific images have become essential to applied research and fundamental research

Full textThis doctoral thesis examines fashion editorials through a case study of three American magazines in context, from the 1960s to the 1980s: Vogue and Harper’s Bazaar, two mainstream publications, and a new magazine then, Interview. It is postulated that the photographic editorial production of those magazines is central to them – as material objects, and as the core of their activity as well, both aspects enabling and unfolding their positions, their codes and their purposes. By looking at major editorial series, I explore how these images stand out as "contact zones" between a highly collaborative production process and their receptions, and how their function is also one of negotiation with regards to its context.A close analysis of the conditions of production, the content and the circulations of these images demonstrates that magazines express undeniable conservatism through the perpetuation of a mainstream norm. However, as this norm constantly changes on the surface, I argue that conditions regularly emerge for it to be negotiated. An attentive study of the tensions and compromises unfolding in the « uncertain moments » that characterize the period running from the 1960s through the 1980s demonstrates the existence of a powerful system. Structured around a coherent and hermetic narrative, it proves indeed hard to challenge. Yet, as this thesis argues, the ensemble of editorial fashion images homogenized by these long-term processes is in fact varied and diverse. If these images construct models, they also offer counter-models, counter-narratives and counter-points. All these possibilities converge into a strict but agile framework, firmly oriented by its producers but adaptable, even though its subversive potential is only realized at the margins.This system—structured around a powerful format—is highly restrictive yet it still performs a constant balancing act between conflicting tensions and goals, fueled by and unfolded in the fashion images at its core

Full textSince the year 2000, the French Senate has hosted documentary photo exhibitions, on the railings lining its gardens. How does this mode of exhibition call into question our relationship to images, their status, their function and their role? Initially, we focused on researchers in semiotics, looking for a theoretical angle from which to approach the empirical study. In the evolution from semio-linguistics to socio-semiotics, two attitudes captured our attention. Certain researchers analyse images as texts (global, recognizable forms). Others approach them as instances of enunciation, as forms taken into account by individuals in specific concrete interactions. We then turned to the visitors as receivers, to study the way the images were received. The public is formed of people who typically visit cultural exhibitions, but who to transgress the behaviour associated with museum visits. This prefigures a new conception of the work of art, as interactive and desacralised. Moreover, interviews with the visitors revealed tensions, in their relationship to the images, between contextualising and textualising, aesthetic and media-centred approaches. On the one hand, the images are considered as a source of pleasure in themselves and, on the other, as a source of information, representations and discourse. Finally, this dual approach to the documentary photos displayed on the railings is suggested by the way the Senate itself presents the exhibition, and the choice of medium. It reflects the ambivalence of the activity carried out by this institution, between cultural politicy and institutional communication

Full textContent-Based Image Retrieval (CBIR) is a discipline of Computer Science which aims at automatically structuring image collections according to some visual criteria. The offered functionalities include the efficient access to images in a large database of images, or the identification of their content through object detection and recognition tools. They impact a large range of fields which manipulate this kind of data, such as multimedia, culture, security, health, scientific research, etc.To index an image from its visual content first requires producing a visual summary of this content for a given use, which will be the index of this image in the database. From now on, the literature on image descriptors is very rich; several families of descriptors exist and in each family, a lot of approaches live together. Many descriptors do not describe the same information and do not have the same properties. Therefore it is relevant to combine some of them to better describe the image content. The combination can be implemented differently according to the involved descriptors and to the application. In this thesis, we focus on the family of local descriptors, with application to image and object retrieval by example in a collection of images. Their nice properties make them very popular for retrieval, recognition and categorization of objects and scenes. Two directions of research are investigated:Feature combination applied to query-by-example image retrieval: the core of the thesis rests on the proposal of a model for combining low-level and generic descriptors in order to obtain a descriptor richer and adapted to a given use case while maintaining genericity in order to be able to index different types of visual contents. The considered application being query-by-example, another major difficulty is the complexity of the proposal, which has to meet with reduced retrieval times, even with large datasets. To meet these goals, we propose an approach based on the fusion of inverted indices, which allows to represent the content better while being associated with an efficient access method.Complementarity of the descriptors: We focus on the evaluation of the complementarity of existing local descriptors by proposing statistical criteria of analysis of their spatial distribution. This work allows highlighting a synergy between some of these techniques when judged sufficiently complementary. The spatial criteria are employed within a regression-based prediction model which has the advantage of selecting the suitable feature combinations globally for a dataset but most importantly for each image. The approach is evaluated within the fusion of inverted indices search engine, where it shows its relevance and also highlights that the optimal combination of features may vary from an image to another.Additionally, we exploit the previous two proposals to address the problem of cross-domain image retrieval, where the images are matched across different domains, including multi-source and multi-date contents. Two applications of cross-domain matching are explored. First, cross-domain image retrieval is applied to the digitized cultural photographic collections of a museum, where it demonstrates its effectiveness for the exploration and promotion of these contents at different levels from their archiving up to their exhibition in or ex-situ. Second, we explore the application of cross-domain image localization, where the pose of a landmark is estimated by retrieving visually similar geo-referenced images to the query images

Full textIn a time when artists claim the totality of objects composing reality as a material source for art, we find it necessary to reflect on the uses of and creative appropriations specific to photographic images. In moving thusly from a general framework to a specific one, we intend to introduce a reflection centered on the use of pre-existing photos in artistic practices that themselves are directed towards the creation of a photographic oeuvre. However, and given the problematics associated with creating from an already-created object, in this case a photo, what is in it of a photographic form that as a subjective expression keeps a link of dependence with the necessity of existence that is precondition of a technical image? What happens when an image of an image enters the world in this context? In this sense, when doing photography becomes redoing from a pre-existing photograph, do we approach photos, photographic processes and procedures in art and finally photographic oeuvres, or even photography and art itself in the same manner? The questions that are developed in this specific context, in response to artworks and with the aid of theories and notions, permit us to identify elements towards an aesthetics of the photographic use of pre-existing photos, and expose us to political, legal, ethical, and other aspects of these actions, placing photos at the center of processes and procedures in photography

Full textThis thesis lies within the framework of the revival of the memory of Spanish Civil War victims, through consideration of one of the myths of contemporary history—Juan Negrín, last head of government of the Second Spanish Republic (1931-1939). This work revisits the circulation of the memory of Juan Negrín in contemporary public space by studying various materials conveying his memory—his private and official correspondence (1931-1937), his memoirs, his photographs and the film productions that have used some of these documents. This thesis is based on a diverse corpus of texts and images gathered as materials reflecting an experience of the self, thus shedding light on Juan Negrín’s viewpoint on the beginnings of the war, the conflict and its aftermath. Through Juan Negrín’s textual and photographic practices, the three parts offer a record both of his sense experience of the period and of his role as a politician and a citizen ahead of his time. This research work investigates the black legend that was built and keeps on being conveyed concerning his memory and his role in political life. Thanks to the various materials analysed, this work is an invitation to consider how the memory of a man is closely linked to collective memory and historical memory

Full textThis research on the insert of pictures is based on an artistic practice which basic caracteristic consists in acting like a mask. Not that mask which makes definitely disappear the lower surface like layers of sediment, but a mask supposed to be lifted up in order to let appear what is never be totally hidden. Those surfaces which mask and those hidden can both be made of different material (fabric, wood, paper, tracing paper), but what remains common among those supports is the fact that they bear a photography, or very often a photocopy. Each creation thus composed is called "photobjet". Those, masks and juxtapositions building up "photobjets" create "inserts" wich can be either places, folds, interstices where is to be found the "one impossible"(un- possible) image also called "the image of light" this insert confronted with pictures and ideas affirmed itself as the main idea in this study whereas the picture, called "un-possible" the would be one concentrating within itself space, reality as will as imagination, is put aside, condemmed into a bottomless abyss. The last chapitre deals with the boarders of this research : between origin and obscenity. Thus, on the one hand, this thesis maintains that striving for the "un- possible picture" in the field of photography, is the desire to reach the origine and, on the other hand, that the characteristics of closeness with the reality and fixeness of this one, turn photography into an object bearing obscenity. This research tried to find the impossible formula of alchemy capable of disturbing our consciousness. This formula is located between knowledge revealed by obscenity and therefore the obligation to approach it from a different angle to avoid paralysis. Therefore to fight back this paralysing "medusa" that photographyis, the practical experience had to find and create different means of escape

Full textThis thesis proposes to define a generation of artists who are collecting, associating and redistributing pictures without changing or transforming the iconic contents. In order to elaborate their characteristics, several french contemporary artists were interviewed: Eric Baudelaire, Ludovic Burel, Hervé Coqueret, documentation céline duval, Pierre Leguillon, Mathieu Pernot, Régis Perray and Eric Watier. The analysis of the devices implemented by the artists shows two aspects that could identify the specificity of their work: their way of associating the pictures with each other offers new possibilities of interpretation and leads to a second reading of the pictures; and their practice is taking place during the transition between the eras of image reproduction techniques and numerical techniques. Within the scope of a multi-field scientific research, it will be necessary to study the creation processes from the choice of the representation till the distribution of the projects (I), to analyse the polysemy of the images and the possibility of rereading their signs (II), and, finally, to understand how the artistic position is located between two, with respect to pictures, technically distinguished epoches (III). To differentiate this generation of artists from others reusing images, the thesis suggests a new name: the “Rereaders of pictures”

Full textThe so-called “Computer Aided Appearance Design” (CA²D), which emerged in the late 1990s, is a branch of CAD dealing specifically with the appearance of materials.CA²D could be a key tool for decision-making in the design phases of manufactured products. However, while nowadays the digital model has almost completely superseded the physical model as far as the choice of shape is concerned, the determination of colours and materials still essentially requires the production of one or more real prototypes. This research workraises the issues of decision-making related to appearance on the basis of a computer-generated image simulation. This pragmatic approach allowing a link between real and virtual provides in this field a new concept that we shall call iso-photographic rendering

Full textOur research focuses on the photographic study of the pinhole, which is approached as a historical, theoretical and experimental object. We questioned the confusion existing between the principle of the pinhole and the phenomenon of the camera obscura. What separates them is sensitive experience and their internal structure. We have thus distinguished the place where the image is formed, from the optical medium which produces it. Beyond their fundamental differences, linked to their respective epistemological and semantic fields, the two devices share the quality of creating an image from light. A camera obscura forms observable images and sometimes allows the drawing of contours. A pinhole produces photographically recorded images. Pinholes and dark rooms have separate technical requirements for implementation. The visual phenomena present in either case can not be confused or assimilated, but must be compared, one after the other, in projected images. The stories of the photographic image presented the dark rooms as one of their founding mythographies. The pinholes invented by photographic modernity at the end of the nineteenth century make a late entry into the histories of optics, physics, vision, chemistry and mechanics. Since the work of Jonathan Crary (1990), a camera obscura can no longer be thought of as an ancestor of cameras, cinema or video. In the United States, since 1995 (Pinhole Resource) a new practice of the pinholes reformulates phenomenologically their history and that of the cameras obscurae. Throughout the ancient sources, several historical data relating to the production of images by light have been verifier. The engravings and the graphic representations of the optical phenomena are central to our approach. We are interested in the sources that address the moment and the place where light becomes an image

Full textThe thesis in Arts that we present associates a personal artistic practice of photography and a research at the crossing of arts sciences, sociology and psychology. It develops an analysis of the representation of work in arts through the use of the photographic medium, from the beginning of the 20th century until today, with a particular interest in the extreme contemporary period. The main stake of this research is to demonstrate how an artistic practice can translate a current event with little visibility, linked to the social representation of work. It focuses on a specific example, the malaise at work, which is the object of both the personal artistic practice and the research work. Whether by the use of portrait or by a staging work, the choices of this artistic representation interrogate the characteristics and the production of meaning of a creative device which combines theatre and still images assembled in polyptyches – while inciting reflexion on a human problem that has become a social phenomenon
De, Jesus Samuel. "Non-lieux. Hors-temps. Pour une iconographie contemporaine et photographique de la saudade." Thesis, Paris 3, 2010. http://www.theses.fr/2010PA030077.
Full textWhich relations can the saudade, major expression of the Portuguese literature of the XVIth century, maintain a priori with contemporary photography? If saudade, phenomenon described by the poet Almeida Garett as a « delicious pain of the heart », born of the puncture of « a cruel spine », wakes up the remembrance related to a beloved being or place – whose absence, lack or loss cause us as much sadness as joy –, remains not easily translatable, and often continues to be comparable with the melancholy. However saudade also appears as a singular thought operating a temporal and spatial synthesis coming from man’s experience of the world, a « virtual » collage governed like a true layout of images. How can this feeling consequently find in photography a place of representation? Which symptoms, which “marks” thus come to reveal us its possible forms of application? Which paradoxes can also emerge, as soon as we try to withdraw them since their dormancy, or to reveal présent by their own absence, all that was, one day, but which is not anymore, or perhaps, the peculiar hope of what has not occurred yet? It is with these main questions that this thesis will try to answer, by exploring a corpus made up mainly among a choice of French and Brazilian contemporary photographs, but does not omit nevertheless other visual sources, such as paintings, engravings, films, performances, or often ephemeral installations. It is also trying to understand how this concept finally comes to compose a photographic iconography of an image-saudade which reveals itself as rich as complex and paradoxal

Full textThe Brazilian photography collection of the Société française de photographie (SFP) consists of 150 photographs, produced between 1940 and 1950 by amateur photographers, formally associated with photo clubs in Brazil. Beyond aesthetic, geographical and institutional affiliations, these images can be divided into two different groups: those sent for participation in the International Salon of Photographic Art in 1951 and those exhibited in February 1960, as part of an exhibition on Brazilian photography, organized at Galerie Montalembert, supported by the SFP. The investigation around the Brazilian collection will involve the articulation of the different analytical paths. The first one corresponds to the process of creating and articulating the first photoclubs in the country, including the organization of the first national fair and the creation of a network between different entities. Concerning the notion of amateur photographer as a reference, the starting point is the "devout" and "deviant" duo proposed by Pierre Bourdieu. The second route addresses the question of the international vocation, a characteristic dear to the first institutions of this type and which remained a fundamental element in the middle of the 20th century. The main public event in the world of amateur photographic art is the fairs. The principles that link different groups of amateur photographers are reflected in the organization of these events based on exchange, thanks to an intense circulation of images, but also by ephemeral recognition. For the third chapter, the scale of the analysis is modified, moving from large events with hundreds of exhibitors to reading images from the specific collection. This is the moment when it will be possible to highlight the main products of the circulation and appropriation process involved in the insertion of amateur photographic art into the world. The fourth chapter focuses mainly on the analysis of the production of the photographers present in the two series (1951 and 1960). The intention is to identify changes and permanencies, seeking to link them to other aspects that have influenced production during this period

Full textThis thesis is based on a very simple evidence: any portrait photographer sends an image back to his model, and no investigation has been done yet on this subject of the feedback of photographic portrait. But this question of the feedback is a constitutive part of of the photographic portrait: while sitting, the model surrenders or not, anticipating a feedback image that will often be sensibly differnet of the one he expected. Starting from this evidence, I revisit history of photography, as well as my own experience as a social photographer, to determine the interactions between photographer and models from this point of view. Photography, by itself indifferent, is revealed only in the stream of intersubjective relationship

Full textAlthough the paparazzi is the poor relation in the history of photography, it is a precious source of inspiration for cinematographic and televisual fictions. Already a character before appearing on screen, the paparazzi establishes a tension, both narrative and visual, that encourages an exploration of its forms of representation. Supported by a collection of films and western television series, from 1940 to 2008, this work will identify and analyze the reoccuring ways in which the paparazzi is represented, from a socio-historical and cultural perspective. Seducer, savior… hunter, thief ? Returning to the imaginary world which surrounds the camera and the hybrid quality of its use allows one to understand how theimage of a « bad » photographer is built. Anonymous croud or main character in the story, half-animal, half-machine, the different faces of the paparazzi on screen both enlighten and threaten the star’s humanity. At a time when the chance of reaching celebrity status are as high as the odds of « acting like a paparazzi », works of fiction reveal a struggle to the deathin which each party fights for a new absolute value : visibility

Full textThe first colour photographs were produced in 1848 by Edmond Becquerel at the Museum of natural History in Paris. The origin of their colours motivated an intense debate between the scientists during the XIXth century. Two main hypotheses were proposed, namely a pigmentary hypothesis and an interferential hypothesis. Nowadays the question of the colours of those photochromatic images is still not settled and this doctoral research aims at addressing it by an experimental approach. We first studied the sensitizing of the silver plate and the exposure of the sensitive surface to light in order to replicate the Becquerel process and to gain information on the photosensitivity of these images. The optical properties of the sensitized and coloured layers were characterized by UV-visible spectroscopy and related to their chemical composition (studied by XAS) and their morphologies, from the micro to the nanoscale (studied by SEM and TEM). A methodological development was necessary to understand and overcome the sensitivity of the samples to photonic beams (UV-visible and X-rays) and electronic beams. The results allow us to reject the interferential hypothesis, which prevailed since the end of the XIXth century. The sensitized and coloured layers consist in micrometric silver chloride grains decorated by silver nanoparticles. Besides, these nanoparticles, which we investigated by low loss EELS, are responsible for the visible absorption of sensitized and coloured layers through surface plasmon resonance. We suggest that the photochromatic images colours have a plasmonic origin and hereby discuss this hypothesis

Full textThe present research interrogates the poetry of the fashion contemporary body transmitted by two media portraying the body : fashion shows and photographic series as part of fashion magazines. At the crossroads of semiotic, discursive political and social issues, the central problem investigated in this thesis is the complex and interdisciplinary point of view of the information sciences of communication with the aim to study the media construction of the fashion world. Three hypotheses divide the investigated problem by taking the mediatised part of the fashion world and produce it as “reified form” of advertisement and culture. The first postulates that fashion shows and fashion series are medias which produce an informed body by the apparatus owned by each of them. The second hypothesis postulates that the fashion body is produced for commercialand advertisement purposes. It does not persist less “culturalized” thanks to the choreography which is perceived as writing of the body in the catwalk space or in the photographic page. This gives it a culture status allowing it to circulate in the social medias. Finally, the third follows the movement of the fashion body's reification initiated by the exposure through fashion shows. It postulates that its mass exposure by photographic series, which is an industrialized and standardized production, make it similar to a merchandise

Full textWe begin by observing the importance of the image in the anthropogenesis’ process because the fixed image reveals temporal mediation, namely, the creation of reported time, mediatizing our relation to the real and thus, transgressing our fields of the perceptual. On this basis, the image’s history appears as a development of various static eidetic models that are going to be in a negotiation and permanent relationship with dynamic eidetic models: language, gestures, equipment, music, dance, the habitat; models that, in return, are mediations enabling us to invest the space and divide it up. The intermingling of the dynamic and static models would constitute the character defining man as a political animal, in the myriad and diversity of the elements that are components for each culture. That is how we are able to detect an ontological difference at the time when the photographic trace appears, a trace not resulting from a formal, symbolic idealization but from an idealization of distance, from which the screen materializes by articulating the eye from a new operative scale. The image’s essential contribution would thus have entered a new phase that would have transformed man into a media animal after almost two centuries. That is where the history of the new trace becomes the core of all political issues in its most consistent manifestation, under the surge of digital technology, that of cinematographic expression.In doing so, we have addressed and favoured one of cinema’s histories at a time when there was a development of specific issues in relation to the real, notably using the work of a Mexican filmmaker, Téo Hernández, mainly done in Europe between 1968 and 1992 as an example. Its powerful phenomenological dimensions — the importance of the body while filming — and also the deep reflexion on the medium and its relation to the real, have provided us with a keystone that enables us to understand the major changes in media that happened during the 1980s and determined the political outlook of the world today

Full textThis study is based on the analyses of images and texts through literatureà à à à à à à à à à à à à ¢ s and photographyà à à à à à à à à à à à à ¢ s works from the years 1850 to 1870 in France. These years have been marked by a contradictory relationship to the nascent photography, at once economical mirage, artistic product, only industrial product, a little bit myth and magic, this invention did leave nobody indifferent. Several actions for the right to the artistic ownership of the photography have been brought and celebrities, like Baudelaire or Ingres, did take positions either for or against the photography. This thesis aims to understand in what consist these contradictions, to elucidate these oppositions and to find the common points to be possibly considered in a diatribe around photography: is it an artistic or industrial product? To go deeply in these aspects, from a textual and iconographical point of view, my choice did concentrate on the work and thought of three artists who did lean on the questions raised by the advent of the photography: Nadar, Baudelaire and Delacroix. A photographer with a an already well known career as caricaturist and journalist, a writer and artà à à à à à à à à à à à à ¢ s critic and a painter who did exploit the various possibilities offered by the very young photography (from the daguerreotype to the positive/negative process on paper). All three of them did entertain an intimate relationship with the photography and took strong positions, sometime looking contradictory, on which I concentrated my research. Their work has been analyzed through their relationship with the photography, either by their works (written or photographic) or by their esthetic and critical approach. This research has been contextual in the cultural France of the Second Empire, especially in Paris and constantly enriched by the testimonies and contributions of other operators from the sector.

Full textThe blur, as a widespread artistic effect, is still victim of a bad reputation, since it is usually considered to be a technical fault or the opposite of a rational and rigorous thinking. Against this reductive vision, this research tries to show, throughout a selection of artworks from Gerhard Richter, Christian Boltanski and Thomas Ruff, that the blur is an artistic act which arouses a distanced and critical reflection. We elaborate a comparative study of each artist's creation process, and an analysis of archival image features appropriated by them : amateur photographs and press images. The blur seems to represent an efficient method of appropriation and détournement. It highlights the image material in spite of its representational function, and it allows to transgress the borders between painting and photography. The blur is also sign of distance : between artworks and spectators, as well as between artists and appropriated images. However, the detachment of artists doesn't prevent them from expressing a critical thinking over images they use. For it is in integrating archival images with topics varying from daily banality and major historic events in their artworks, that the artists examine the social uses and the media reproduction of images. But the blur proved mainly to be a strategy to cross the borders between shape and material, objectivity and subjectivity, or mass culture and fine art. It is above all, a dynamic concept used for transgression
