Dual photography

Pradeep Sen, Billy Chen, Gaurav Garg, Stephen R. Marschner, Mark Horowitz, Marc Levoy, Hendrik P. A. Lensch
2005 ACM SIGGRAPH 2005 Papers on - SIGGRAPH '05  
Using an array of cameras we can produce a 6D slice of the 8D reflectance field that allows for relighting with arbitrary light fields.  ...  Since an array of cameras can operate in parallel without interference, whereas an array of light sources cannot, dual photography is fundamentally a more efficient way to capture such a 6D dataset than  ...  Elizabeth Chen made many of the box models shown in the results. Yasamin Mostofi and John Owens proofread drafts of the paper. The animated model for Figure 15 was provided by Mark Kilgard.  ...

They have very good depth of focus at full aperture, which shortens the necessary exposure, yielding a fully-timed plate when, as with “wiggly ” children, one has to “ cut it short.”  ...  When it comes to take the “grown-ups,” who can keep their pose for a longer exposure, at once the field broadens. Here is your chance to try some of the “ Unconventional Lightings,” described by Mr.  ... 

The Semiotics of Photography: Towards Objective Hermeneutics

established for a reliable and clear judgment to discriminate one photo from another?  ...  For critics or judges, artists or the general public, this article seeks to answer these questions by proposing a semiotic analysis based on new advances in science, in psychology of perception and neurobiology  ...  Depth of field varies primarily with the lenses' aperture and, in turn, depends on the format and distance of the focus.  ...

DIGITAL DENTAL PHOTOGRAPHY: THE GUIDELINES FOR A PRACTICAL APPROACH

Rafey Fahim, Rachna Thakur, Reader
TMU J. Dent   unpublished
This article offers a brief history of digital photography along with the basic elements and techniques implemented for the better results.  ...  Photographs of a patient's face provide a significant amount of information to aid diagnosis and treatment planning as well as to document preoperative and postoperative conditions.  ...  Conventional lighting approaches using ring-flash or two studio flashes shining 45 degrees on each side of the face could result in the flattening of the depth of facial structures.  ...
