Wissenschaftliche Photographie als visuelle Kultur. Die Erforschung und Dokumentation von Spektren

This paper discusses facets of 19th‐century scientific photography as a visual culture. The example of spectral research and documentation is particularly well suited, because prismatically diffracted light from the sun or from luminous gases was one of the most frequently examined phenomena of that century. The results were significant not only for physics but also for analytical chemistry and astrophysics. The spectrum also served as an ideal test object for checking the effectiveness of a wide array of photochemically sensitizable surfaces to the various color regions. Scientific photography became the most important experimental technique in the infrared and ultraviolet. H. A. Rowland's spectrum charts are discussed as an example of the transition from comprehensiveness in documentation to fetishism. The discussion of the Lippmann process, one of the first methods of color photography, addresses the associated training of the eye. Issues of authenticity and the much averred ?mechanical objectivity”? are raised with regard to retouching. The overriding theme of visual science cultures leads furthermore to unanticipated interdependencies with other scientific fields, such as geography, and draws the importance of practitioners into the foreground.

High Dynamic Range Imaging for Archaeological Recording

This paper notes the adoption of digital photography as a primary recording means within archaeology, and reviews some issues and problems that this presents. Particular attention is given to the problems of recording high-contrast scenes in archaeology and high dynamic range imaging using multiple exposures is suggested as a means of providing an archive of high-contrast scenes that can later be tone-mapped to provide a variety of visualisations. Exposure fusion is also considered, although it is noted that this has some disadvantages. Three case studies are then presented: (1) a very high-contrast photograph taken from within a rock-cut tomb at Cala Morell, Menorca, (2) an archaeological test pitting exercise requiring rapid acquisition of photographic records in challenging circumstances and (3) legacy material consisting of three differently exposed colour positive (slide) photographs of the same scene. In each case, high dynamic range (HDR) methods are shown to significantly aid the generation of a high-quality illustrative record photograph, and it is concluded that HDR imaging could serve an effective role in archaeological photographic recording, although there remain problems of archiving and distributing HDR radiance map data.

From Photography to Cinematography: Recording Movement and Gait in a Neurological Context

The major challenge of photography has been freezing movement, to transform it into a fixed image or series of images. Very soon, photographers became interested in movement itself and tried to use photography as a tool to analyze movement. At the early stages, physicians interested in movement, perhaps surprisingly, made important technical contributions. Mécanisme de la physionomie humaine, by Duchenne, the first book with physiological experiments illustrated by photographs, is a landmark in this historical development. At the Salpêtrière, thanks to Charcot, photography officially entered clinical neurology. Medical journals with photographs were actively developed by Bourneville. Londe established a clinical photographic laboratory and published the first book on medical photography. The study of animal and human movement by Muybridge and Marey in the 1880s led to chronophotography and later cinematography. Clinicians such as Dercum and Richer took advantage of these new techniques to study pathological movement and gait in neurological diseases.

Using photography in research with young migrants: addressing questions of visibility,movement and personal spaces

This article discusses the experience of using photography in a research project with young (prospective) migrants in Ghana and Italy. Photography can be an empowering research tool, one that offers young participants a degree of control over the research process and thus allows their points of view to emerge. However, researchers need to consider that the choice of subjects may be influenced by the children’s desire to avoid taking photographs in public, as they may attract attention and the act of pointing a camera may provoke unwanted questions and comments. Moreover, young people often lack the means to move independently, and this may further restrict the subjects they are able to photograph. Finally, they may resent adults’ intrusion into their free time and therefore see taking photographs as a chore. I argue that all these factors need to receive greater attention when choosing photography in research with young participants.     

PHOTOGRAPHS, SYMBOLIC IMAGES, AND THE HOLOCAUST: ON THE (IM)POSSIBILITY OF DEPICTING HISTORICAL TRUTH

Photography has often been scrutinized regarding its relationship to reality or historical truth. This includes not only the indexicality of photography, but also the question of how structures and processes that comprise history and historical events can be depicted. In this context, the Holocaust provides a particular challenge to photography. As has been discussed in numerous publications, this historic event marks the "limits of representation." Nevertheless there are many photographs "showing" the Holocaust that have been produced in different contexts that bespeak the photographers' gaze and the circumstances of the photographs' production. Some of the pictures have become very well known due to their frequent reproduction, even though they often do not show the annihilation itself, but situations different from that; their interpretation as Holocaust pictures results rather from a metonymic deferral. When these pictures are frequently reproduced they are transformed into symbolic images, that is, images that can be removed from their specific context, and in this way they come to signify abstract concepts such as "evil." Despite being removed from their specific context these images can, as this essay argues, refer to historical truth. First, I explore the arguments of some key theorists of photography (Benjamin, Kracauer, Sontag, Barthes) to investigate the relationship between photography and reality in general, looking at their different concepts of reality, history, and historical truth, as well as the question of the meaning of images. Second, I describe the individual circumstances in which some famous Holocaust pictures were taken in order to analyze, by means of three examples, the question what makes these specific pictures so particularly suitable to becoming symbolic images and why they may—despite their abstract meaning—be able to depict historical truth.     

The Evil Eye and Cultural Beliefs among the Bedouin Tribes of the Negev,Middle East [1]

This paper examines Bedouin attitudes and practices relating to the evil eye as a cause of misfortune. The evil eye is perceived by the Bedouin as one of the most dangerous forces that can interfere in their lives, and they invest much energy in a variety of methods to counteract it. This paper seeks to contribute to a better understanding of the phenomenon by describing the rituals of diagnosis, treatment and prevention among the Bedouin tribes of the Negev in the Middle East.

The evil eye can bring a man to his grave, and a camel to the cooking pot (Arab-Bedouin saying).

The evil eye is like a light. You can see it, feel it, be affected by it, or affect others by means of it. It can cause harm or even death in large numbers, but you never succeed in holding it in your hands. This is the will of Allah (Bedouin saying).     

Capturing Motion and Depth Before Cinematography

Visual representations of biological states have traditionally faced two problems: they lacked motion and depth. Attempts were made to supply these wants over many centuries, but the major advances were made in the early-nineteenth century. Motion was synthesized by sequences of slightly different images presented in rapid succession and depth was added by presenting slightly different images to each eye. Apparent motion and depth were combined some years later, but they tended to be applied separately. The major figures in this early period were Wheatstone, Plateau, Horner, Duboscq, Claudet, and Purkinje. Others later in the century, like Marey and Muybridge, were stimulated to extend the uses to which apparent motion and photography could be applied to examining body movements. These developments occurred before the birth of cinematography, and significant insights were derived from attempts to combine motion and depth.     

Visualisierungen in der deutschen Geographie des 19. Jahrhunderts. Die Beispiele Robert Schlagintweit und Hans Meyer

Visualization in 19^th‐century German geography: Robert Schlagintweit and Hans Meyer as examples. – Visual representations of nature formed an essential part of 19^th‐century earth sciences. In particular, colonial photography – as a visual source, and as an instrument of the construction of national identities – serves essential research interests of current history and social sciences. The present paper is a case study on the role and function of photography in German geography of the 19^th and early 20^th centuries. It focuses on the work of the Munich geographer Robert Schlagintweit (1833–1885) and the Leipzig colonial geographer Hans Meyer (1858–1929); the early history of photography in India and the function of images in the geographical exploration of overseas territories are discussed. Although there is nearly half a century between the work of R. Schlagintweit and H. Meyer, their photography shows remarkable parallels. The ideas of both on the practice of visualization are rooted in pedagogic and didactic concepts as well as in popular science. For both geographers photography was essentially a technical help, which often needed graphic revisions. And they both preferred photography to depict people and buildings (compared, for instance, to landscapes). Concerning the more comprehensive question of how far their photography transmitted a specific German ‘image of abroad’, it is indicated that such a specific image should have its essential roots in a peculiar visual culture of German earth sciences in the first half of the 19^th century. Thus the paper offers a starting point for further studies discussing the change from a ‘Biedermeier image’ of foreign cultures to a more ‘colonial’ one in 19^th‐century German geography.     

Ophthalmoscopy in Charlotte Brontë's Villette

This essay re-examines the representation of scopic conflict and discipline in Charlotte Brontë's novel, Villette (1853), within the context of the reconfiguration of the eye during the 1850s. Villette is pioneering in its representation of an ophthalmoscopic conception of the eye, as an organ which could be looked into by medical practitioners as well as looked at. This notion of the eye was only possible after Hermann von Helmholtz's invention of the ophthalmoscope in 1850. Villette is thus one of the first literary responses to the newly visible living retina. This essay argues that in light of the novel's emphasis on a penetrable, legible eye, the critical emphasis that scholars have placed on surveillance as a disciplinary model in Villette is overstated. Visual exchanges are described not in the disembodied abstractions of panopticism, but with references to a violent lexicon derived, in part, from the novel terminology of ophthalmoscopy. The prominence of opthalmoscopy points towards a remedial narrative in which diagnosis is succeeded by surgical intervention, and ultimately the restoration of sight. M. Paul Emanuel is the principal emblem of this visual practice: a merciless autocratic ophthalmologist who brings pain but also palliation. Villette's remedial narrative is organized around three devices designed to respectively look into, perforate, and enhance the human eye: the ophthalmoscope, the stylet (an instrument used in eye-surgery), and spectacles. This analysis adopts a historicist approach to re-contextualize Brontë's imaginative depiction of optical technology and perception within the mid-century emergence of ophthalmology.     

REPORT Neurology of the Arts Mansell Bequest Symposium at the Medical Society of London 30 April–1 May 2001

Philosophical instruments were designed to examine phenomena experimentally, rather than by naturalistic observation alone. In the nineteenth century, some instruments were called philosophical toys because they provided popular amusement as well as experimental assistance. They were applied widely in natural philosophy, but attention here is directed particularly to manipulations of perceived space and time and their influence on art. One of the earliest instruments, which had a profound impact on art as well as science, was the camera obscura. It assisted image formation in art before it was applied as an analogy to the eye at the beginning of the seventeenth century. Later philosophical toys were used to address visual perception of motion and depth. Development was initially driven by the need for stimulus control so that the methods of physics could be applied to the study of perceptual phenomena. The principal instruments were invented in the first half of the nineteenth century, and they consisted of simple contrivances that manipulated time and space in ways that had not previously been appreciated. They included thaumatropes, phenakistoscopes, stroboscopes, anorthoscopes, stereoscopes, tachistoscopes, and chronoscopes. Several of these philosophical toys proved to be phenomenally popular, particularly when combined with photography.

X射线摄影技术在漆下彩画识别中的应用

针对遭到油漆涂抹的传统彩画作品,为了实现对图案的无损提取,本研究使用X射线摄影技术,又称X光成像(照相)技术,利用X射线对不同物质的穿透能力有别,在底片上成像的灰度与物体材质、密度、厚度等密切相关的特点,最终得到分界清晰的黑白图像。此类病类常见于建筑彩画中,建筑彩画意蕴深厚、技法繁缛,极具研究价值,但其中很多关键信息却已失传。经X射线摄影技术辅助,封存在油漆层下的彩画图案得以重见天日,此法与其他修复方法之间形成互补,为漆下彩画的完美修复提供了可能。     

WHY PHOTOGRAPHY MATTERS TO THE THEORY OF HISTORY

Georges Didi-Huberman's study is concerned with epistemological and ethical questions that arise from visual representations of the Shoah, while Michael Fried's is concerned with the ontological possibilities explored by contemporary art photography. The books have two things in common: an argument against postmodern skepticism, and an insistence that photography has become a field in which questions of history, truth, and authenticity are being explored with particular acuity. Rather than reject even the possibility that photographs have something to tell us about the Shoah, Didi-Huberman shows that they can offer important insights into the difficulties and the possibilities of apprehending some aspects of the past.
Fried shows that contemporary photographic work has taken on the ambitions of high modernism by accepting the challenge of "to-be-seenness." Photography as a "historical practice" does not escape from the difficulties of evidence and of the "constructed" nature of historical understanding; photography functions neither as a pure trace of the past, nor as a mere invitation to spectacle.     

Preliminary remarks on George Seferis' visual poetics

Abstract

This article makes some preliminary remarks on Seferis' photography, focusing mainly on its poetics as an act of seeing. The main intention is to highlight the direct relationship between Seferis' visual sensibility and his poetry. The article primarily discusses some technical features of Seferis' photography. It then examines his photography as a visual diary and draws attention to those cases where it is obvious that photographs hide behind specific poems. Finally, the article discusses the differences between photography and poetry regarding their relation to time. In this context, the poem 'M? τov τρóπo τov Γ.Σ.', which makes explicit reference to photography, is examined.
