We look at how a seemingly small change in the photographic process—capturing a focal stack at the press of a button, instead of a single photo—can boost significantly the optical performance of a conventional camera. By generalizing the familiar photographic concepts of “depth of field” and “exposure time” to the case of focal stacks, we show that focal stack photography has two performance ad...

Aerial photogrammetry is one of the main methods obtaining geospatial information. After entering the 21st century, aerial photogrammetry technology has fully entered the digital age, and the quality of digital aerial photography results will directly affect the quality and accuracy of results of surveying and mapping .Therefore, it is necessary to inspect the quality of digital aerial photogra...

OBJECTIVES To provide the practicing surgeon with data to make an informed economic decision regarding conversion from analog to digital photography. METHODS A cost analysis of photography based on 35-mm vs digital platforms (low-, medium-, and high-cost hardware). RESULTS Break-even thresholds for the investment in a digital platform of low, medium, and high costs were 3674, 15,789, and 34...

The emerging field of computational photography is exploring the possibilities of digital photography beyond the imitation of film cameras. Novel illumination, optics, sensors, and processing methods are employed to expand the set of images that cameras can create. This thesis introduces the field of computational photography and presents two exemplary techniques that address the problem of blu...

In our original article evaluating symmetry in breast reconstruction, we evaluated the role of three-dimensional digital photography.1 Women were stratified into two groups, those who had three-dimensional photography and those who did not. Comparisons included initial volume and contour symmetry, secondary procedures, and final volume and contour symmetry. It was concluded that three-dimension...
