Visiting ruins, I enjoy the texture of the weathered stones. The wide space, colored in spring by wildflowers. Open space and vistas, the heady smell of grasses drying in the hot sun. Birds sing as they have since Plato's cicadas. Once, alone near the ruins, I heard a strange rhythmic clicking in the grass: two tortoises making love. The ruins that I visit remind me of antiquity not because I picture Socrates walking through the Stoa, but because I picture him walking along the still undeveloped riverbank, smelling these grasses, listening to these birds. The simplicity that I long for, however, is not millennia away, but only centuries. It is almost at arms’ length, but just out of view. What I find there is nature in a frame of culture. Like most tourists, I cannot transform the stones into the imaginary film of antiquity that the European brain of the nineteenth century, steeped in a classical education, projected onto them. Yet their vision was no more authentic than mine: in order to project the past onto stones, they had to erase the present.

AbstractCritics of the proposal that the Dutch painter Johannes Vermeer used the camera obscura extensively in making his pictures of domestic scenes have argued that this cannot be the case, since his compositions are not 'photographic snapshots' but are very finely judged and balanced; his subject matter draws on the traditional motifs of Dutch genre painting; and the pictures are filled with complex allegorical and symbolic meaning. In this paper it is argued that all these are indeed characteristics of Vermeer's oeuvre, but that the artist produced them through the transcription of optical images of tableaux, set up by arranging real furniture and other 'props' with extreme care, in an actual room in his mother-in-law's house.

<p>This thesis creatively explores the architectural implications present in the photographs by New Zealand photographer Marie Shannon. The result of this exploration is a house for Shannon. The focus is seven of Shannon's interior panoramas from 1985-1987 in which architectural space is presented as a domestic stage. In these photograph's furniture and objects are the props and Shannon is an actress. This performance, with Shannon both behind and in front of her camera, creates a double insight into her world; architecture as a stage to domestic life, and a photographers view of domestic architecture. Shannon's view on the world enables a greater understanding to our ordinary, domestic lives. Photography is a revealing process that teaches us to see more richly in terms of detail, shading, texture, light and shadow. Through an engagement with photographs and understanding architectural space through a photographer's eye, the hidden, secret or unnoticed aspects to Shannon's reality will be revealed. This insight into another's reality may in turn enable a deeper understanding of our own. The methodology was a revealing process that involved experimenting with Shannon's panoramic photographs. Models and drawing, through photographic techniques, lead to insights both formally in three dimensions and at surface level in two dimensions. These techniques and insights were applied to the site through the framework of a camera obscura. Shannon's new home is created by looking at her photographs with an architect's 'eye'. Externally the home acts as a closed vessel, a camera obscura. But internally rich and intriguing forms, surfaces, textures and shadings are created. Just as the camera obscura projects an exterior scene onto the interior, so does the home. Shannon will inhabit this projection of the shadows which oppose 30 O'Neill Street, Ponsonby, Auckland; her past home and site of her photographs. Photographers, and in particular Shannon, look at the architectural world with fresh eyes, free from an architectural tradition. Photography and the camera enable an improved power of sight. More is revealed to the camera. Beauty is seen in the ordinary, with detail, tone, texture, light and dark fully revealed. As a suspended moment, a deeper understanding and opportunity is created to observe and appreciate this beauty. Through designing with a photographer's eye greater insight is gained into Shannon's 'reality'. This 'revealing' process acts as a means of teaching us how to see pictorial beauty that is inherent in our ordinary lives. This is the beauty that is often hidden in secret, due to our unseeing eyes. This project converts the photographs beauty back into three dimensional architecture.</p>

AbstractIn developing a new theory of vision in Ad Vitellionem paralipomena (1604) Kepler introduced a new optical concept, pictura, which is an image projected on to a screen by a camera obscura. He distinguished this pictura from an imago, the traditional image of medieval optics that existed only in the imagination. By the 1670s a new theory of optical imagery had been developed, and Kepler's pictura and imago became real and virtual images, two aspects of a unified concept of image. The new concept of image developed out of a synthesis of Kepler's determination of the geometrical location of a pictura as the limit, or focus, of refracted pencils of rays and the triangulation used by a single eye to determine the perceived location of an imago. The distinction between real and imaginary images was largely developed by Gilles Personne de Roberval and the Jesuits Francesco Eschinardi and Claude François Milliet Dechales.
