The photographic art project “Panorama Time” is discussed through a techno-cultural perspective and examines the spatial-temporal dimension in panoramic photography, which, in this case, is a digital camera in a mobile phone. The post-media condition and its characteristic of embracing the fusion of different media in one device without specifying any single one is examined in our project through the combination of photographic and cinematographic processes combined in the mobile device. The rolling shutter feature, which is the technological core of digital cameras, enables the strip-photography technique, in our case used in a panoramic technique to deliver a set of concepts: glitch, repetition, frozen frames, and similar. Through deliberate navigation and control, the user breaks the panoramic view, and thus the project’s technique presents the distinction between fault and glitch aesthetics. We show examples and demonstrate the process of creating our digital photography art project “Panorama Time”. -

Institutionally, the answer is obviously yes. Our art museums and galleries abound in photography, and our scholarly jour- nals lavish photographs with attention once reserved for work in other media. Although many contemporary artists mix photography with other tech- nical methods, our institutions do not require this. Th e broad affi rmation that photographs can be art, which comes after more than a century of disagreement and doubt, fulfi lls an old dream of uniting creativity and industry, art and automatism, soul and machine. -
Panoramic Cameras I Built Over the Years
PANORAMIC CAMERAS I'VE MADE Andrew Davidhazy, Imaging and Photographic Technology Rochester Institute of Technology My experiences with panoramic camera construction started in the late 1960's while still an undergraduate student at R.I.T. and while involved with exploring the photographic possibilities of moving film type cameras generically known as "strip" cameras. I first learned of the pictorial applications of these cameras from the work of Life Magazine's George Silk and his coverage of the 1960 Olympics with a camera modified for him by Marty Forsher. The first panoramic camera I built consisted of a mechanism for rewinding the film in a standard 35mm camera while the camera was manually panned at a rate controlled by the focal length used on the camera. The longer the lens the slower the pan for a given rewind speed. I took an approach to determining the length of film required for a full 360° shot which was, and remains, rather unorthodox. Instead of using the traditional formula of 2 x f x pi, I divide the vertical angle of view of the lens in use into 360 and multiply this figure by 24mm. While normal focal length lenses require similar lengths by each method it was not until I came in contact with Cirkut photographers that the advantages of the previous method became evident. At the same time that my interest in panoramic photography increased I started to experiment with enlargements. In 1970 I made a 360° 32 foot long print from a panoramic photography made with a 35mm focal length lens on the above camera turned by a battery driven rotating tripod head made for it. -
