PURPOSE To assess agreement between digital and film photography for research classification of diabetic retinopathy severity. METHODS Digital and film photographs from a 152-eye cohort with a full spectrum of Early Treatment Diabetic Retinopathy Study (ETDRS) severity levels were assessed for repeatability of grading within each image medium and for agreement on ETDRS discrete severity level...

Electronic photography is gaining parts of the photography market and tends to replace gradually all argentic photography. The combination of digital camera and computer technologies have allowed to provide new services like visualising quickly snapshots on a computer with the possibility of direct snapshot touch up or printing. Lately the apparition of a new type of memory proposes the extensi...

High Dynamic Range (HDR) imaging has revolutionized the digital imaging. It allows capture, storage, manipulation, and display of full dynamic range of the captured scene. As a result, it has spawned whole new possibilities for digital photography, from photorealistic to hyper-real. With all these advantages, the technique is expected to replace the conventional 8-bit Low Dynamic Range (LDR) im...

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...

Multi temporal aerial photography and airborne hyper spectral imagery have been integrated for the detection and monitoring of coal mining subsidence hazards. Digital elevation models derived from successive epochs of aerial photography provide estimates of topographic change which may be indicative of the collapse of abandoned underground mine workings in the study area. Ground disturbed by su...

Photography and imaging have been radically transformed over the past couple of decades in ways that 19th-century pioneers such as Louis-JacquesMandé Daguerre (Figure 1) and Henry Fox Talbot could have scarcely imagined. Traditional photography and imaging, rooted in chemical processes, have now largely given way to digital methodologies and technologies. The result has been faster, less expens...

INTRODUCTION Outcome measures of breast reconstruction have used panel assessment of photographs. This provides limited information to the assessor as these images are static.. The aim of this study was to assess whether the use of digital video was a valid assessment tool and to compare its use against photography. METHODS 35 patients post-reconstruction underwent photography, digital video ...
