A general exposition of the scientific potentialities and analytic framework of space photography is presented using the photography of Mars from flybys and orbiters as the principal example. Space photography is treated here as a communication process in which planetary scene information is communicated to the eye-brain receiver of earth-based interpreters. The salient parameters of this proce...

AIMS To assess the effects of (1) mydriasis and (2) single versus three field photography on screening for diabetic eye disease using digital photography METHOD Slit lamp examination findings were compared to digital fundal photographs for the detection of any retinopathy and for referable retinopathy in 398 patients (794 eyes). A Topcon TRC-NW6S digital non-mydriatic fundus camera was used. ...

UNLABELLED The emerging market of digital cephalographs and computerized cephalometry is overwhelming the need to examine the advantages and drawbacks of manual cephalometry, meanwhile, small offices continue to benefit from the economic efficacy and ease of use of analogue cephalograms. The use of modern cephalometric software requires import of digital cephalograms or digital capture of analo...

In her article "Photography in Wang's Chang Hen Ge (Song of Everlasting Sorrow)" Hong Zeng analyzes Wang's novel in the context of imagery following the theoretical framework of photography as proposed in the work of Xun Lu and Roland Barthes. According to both Xun Lu and Roland Barthes, the spectacle of photography is tied to the notion of the "the theater of the dead." Further, according to W...

The first edition of Ophthalmic Photography, published in 1997, was an ambitious undertaking that attempted to gather all aspects of retinal photography and angiography into one volume. The result was a comprehensive yet accessible book that has become a valuable reference for ophthalmic photographers worldwide. Five years have passed since publication of the first edition, and while the fundam...

Purpose To evaluate the development of central atrophy in eyes with age-related macular degeneration (AMD). Methods Six-year longitudinal multimodal retinal imaging data (MODIAMD study) from 98 eyes of 98 subjects with non-late-stage AMD in the study eye at baseline were analyzed for the presence of central atrophy at each annual follow-up visit. Development, manifestation, and further progre...

Capable of three-dimensional imaging of the cornea with micrometer-scale resolution, spectral domain-optical coherence tomography (SDOCT) offers potential advantages over Placido ring and Scheimpflug photography based systems for accurate extraction of quantitative keratometric parameters. In this work, an SDOCT scanning protocol and motion correction algorithm were implemented to minimize the ...

The goal of cosmetic and reconstructive breast surgery is to create symmetric and aesthetically pleasing results in a reproducible manner. Although continued progress is dependent on the ability of plastic surgeons to accurately assess surgical outcomes, available methods to objectively evaluate aesthetic and reconstructive breast surgery are limited. This is quite different from other areas of...
