Pitfalls in colour photography of choroidal tumours.

Colour imaging of fundus tumours has been transformed by the development of digital and confocal scanning laser photography. These advances provide numerous benefits, such as panoramic images, increased contrast, non-contact wide-angle imaging, non-mydriatic photography, and simultaneous angiography. False tumour colour representation can, however, cause serious diagnostic errors. Large choroidal tumours can be totally invisible on angiography. Pseudogrowth can occur because of artefacts caused by different methods of fundus illumination, movement of reference blood vessels, and flattening of Bruch's membrane and sclera when tumour regression occurs. Awareness of these pitfalls should prevent the clinician from misdiagnosing tumours and wrongfully concluding that a tumour has grown.

Time exposure photography of smoke plumes /

The advantages of using time exposures to "integrate" plume behavior have been known for some time. The purpose of this writing is to acquaint the research worker with more comprehensive techniques of long (up to nine hours) time exposures, with several illustrations.

Where Do Flappers Fit In?: The Photography of Modern Fashion in Australia

The visual technique of fashion photography is examined which taught Australian women to look modern. Especially fashion photography intervenes ambivalently into the story of Australian modernism and modernity. During 1920s and 1930s within the fashion press there were synergies and differences between commercial fashion photography, celebrity and cinematic portraiture, and social set endorsement. However, modernism was widely acknowledged in Australia during the 1920s through women's spaces, their fashions and culture of department stores.

Camp et Forêt suivi de Quatre objets de mémoire

Camp met en présence un officier nazi et ses Juifs : une petite fille s’appuyant sur sa vie d’avant afin de survivre dans sa vie d’après, une jeune femme d’une cinglante liberté intérieure et un groupe de prisonniers, la masse grise. Ce récit se déroule en quelques jours dans un camp d’extermination, en Pologne. Il y est question d’un projet insensé, imaginé et mis en œuvre par le Nazi dont le discours s’apparente à de confuses et dérisoires logorrhées. La recherche d’une humanité déniée, à la base du dévoilement de l’individualité des personnages (prisonniers), émane de la grâce, de l’authenticité et de la force vitale de la protagoniste, la petite fille, tendue vers son plan-de-quand-même-vie. Forêt, écrit en parallèle, puis à la fin de Camp, n’est pas sa suite, mais l’est aussi… Court récit poétique, il raconte la traversée d’une forêt par une femme à la recherche de ses édens. Le lieu, interpellé et très souvent conspué pour ce qu’il est devenu, devient un actant. Forêt, se servant de ses restes mythiques, contraint le pas-à-pas de la femme, perdue d’avance. L’essai, Quatre objets de mémoire, porte sur l’appropriation et la transmission de la mémoire de la Shoah, à partir de restes, de détails, de petits riens, perçus ici comme d’imaginables traces. J’interroge les signes singuliers d’improbables objets (feuillets administratifs du Troisième Reich, clichés fragmentaires d’Auschwitz-Birkenau et photographies de ses bois et de ses latrines) afin d’y débusquer de petits morceaux du caché, du secret et de l’innommable de la Solution finale. L’affect ressenti en présence de ces objets, par ce que je nomme, le nécessaire abandon, y est analysé dans le dessein d’en saisir leurs douleurs et de les rendre miennes. L’œuvre de l’artiste de la photo, Marie-Jeanne Musiol, sur Auschwitz-Birkenau, est à la base de ce désir de mémoire pérenne.

Photo-excess : two paradigms of archaeological photography

Discovering ‘photo-excess’: what difference does digital photography bring to the archaeological process, and does this difference constitute a paradigm shift from the traditional film model? Using reflexive practice, the contribution that digital photography has made to the archaeological process is explored. The themes presented in the photographs and exegesis combine visual exploration and original research to examine the role and place of archaeological photography in both a contemporary and an historical context. In contrasting the development of film-based photography of archaeology undertaken in the Eastern Mediterranean during the early 1900s with contemporary digital photography, this exegesis and creative work explores both the synergies and differences of the two photographic methods in archaeology. I introduce the term ‘photo-excess’ to describe the new role that digital photography plays in archaeological practice as compared to film, and demonstrate this difference through my creative work. At the turn of the 20th century, photography was affirmed as the major instrument for visual recording of an archaeological excavation. The combination of archaeological methods and photographic techniques from that era formed an approach to archaeological documentation and recording that was formalised by William Matthews Flinders Petrie in 1904. In this thesis I propose that Petrie became the father of modern archaeological photography through his work, and in recognition of his contribution I refer to his method as the ‘Petrie Paradigm’. Digital photography has made possible a quantum leap in the volume, quality and immediacy of visual data available to the user. Further, through the creative process, digital archaeological photography may provide visual information that exceeds the archaeologist’s original research questions, so that the digital image may sometimes exceed its primary role as a recording device. In such cases it may become the starting point for new research due to its potential photo-excess. I propose this as an emerging paradigm for archaeological photography.
