Rotating Scheimpflug imaging technology is used by instruments such as the Pentacam (Oculus) to measure the anterior and posterior corneal surfaces, as well as other anterior segment structures. Initially, Scheimpflug photography was used to obtain images of lens opacities for objective evaluation, but Pentacam-Scheimpflug camera is much wider in its clinical applications as a diagnostic tool f...

Photography evidences presence, but what does it present? This article explores the notion of magic in photography through Deleuze and Guattari’s concept ‘haecceity’, Jacques Derrida’s logic ‘supplement’ Jean-François Lyotard’s ‘inhuman’. The sections ‘The Zone Photography’, ‘Ghosts in/of Machine’, Crypt Encryption’, ‘Affect-Event-Haecceity’ ‘Magic, Consumerism, Desire’ consider how provides a ...

BACKGROUND Our previous experience monitoring nevi in high-risk patients using serial digital epiluminescence microscopy (DELM) photography achieved low biopsy rates but was limited by melanomas presenting as new lesions or arising from nevi that had not been photographed. OBJECTIVE To determine whether biopsy rates, efficiency of melanoma detection, and melanoma origin (de novo vs nevus deri...

This paper describes an Augmented Reality (AR) system for the treatment of acrophobia. First, the technical characteristics of the first prototype are described. Second, the capacity of the immersive photography used in the AR system to provoke sense of presence in users is tested. Forty-one participants without fear of heights, walked around a staircase in both a real environment and an immers...

The proficiency of nonophthalmologists with direct ophthalmoscopy is poor, which has prompted a search for alternative technologies to examine the ocular fundus. Although ocular fundus photography has existed for decades, its use has been traditionally restricted to ophthalmology clinical care settings and textbooks. Recent research has shown a role for nonmydriatic fundus photography in nonoph...

Experiments on evaluating and improving the mechanical configuration and target illumination in a prototype camera-based ballot counter are presented. The constraints on the mechanical design are gravity paper feed, portability, ease of use and low cost. The constraints on illumination are dictated by image processing requirements. Initial results are reported on the effects of transparent ball...

HISTORICAL.-Monochrome photography of the human retina has been practised increasingly since the early pioneer work on this subject in the latter half of the 19th century. The instrument in most common use to-day is the Zeiss-Nordenson retinal camera, which first appeared in 1915. Several modifications of the original instrument have since appeared, and over 10 years ago it was reported that ab...

Since the late 1970's, dozens of researchers, scholars, skeptics and "professional debunkers" have presented their theories on how the image on the Shroud of Turin was formed. Some are based on serious science while others show a complete lack of understanding of the Shroud image or its properties. In this paper, I will review the "proto-photography" theory proposed by Prof. Nicholas Allen of S...
