December 2006 COBA Meeting

The December 2006 of the Camera Owners of the Bay Area (COBA) user group will be held on Wednesday, December 13, 2006 in Cordura Hall 100 at Stanford University from 7:30-10:00 pm.

NOTE: Due to scheduling conflicts, Uwe Steinmueller will not be able to present his findings of the Leica M8. We hope to have this rescheduled for a date in 2007.

Refocusing Photographs After the Fact

Every photographer is familiar with the frustration of losing a shot because the camera focused too slowly, or focused on the wrong thing. Recent camera technology innovations at Stanford University provide a new solution to this old problem. The idea is to capture extra information at the sensor, which is missing in conventional cameras. Special processing enables physical functions of the lens to be implemented in software.

This approach provides unprecedented photographic features, such as the ability to refocus photographs after the image is taken. The underlying technology also enables dramatic improvements in lighting and sensitivity. For the novice, this means a more reliable camera that makes it easier to take great-looking pictures. For aficionados and professionals, this technology means unprecedented control over the quality of each image pixel.

In this talk, Ren Ng of Refocus Imaging, Inc. will present photographs taken with a prototype camera, discuss how it works and how he believes it will affect photographic science and art.

His research has been featured in the press, including Wired, Popular Science, Digital Photography Review, KNTV-NBC11 TechNow, KTVU-TV Fox 5 News, Photonics Spectra, MIT Tech Review, Stanford Review, slashdot, engadget, and more.

Speaker Bio

Ren Ng recently graduated with his PhD from the Computer Science department at Stanford University, and founded Refocus Imaging to commercialize his research. His PhD dissertation won the Arthur Samuel Thesis Award for the best dissertation in Computer Science at Stanford, and was nominated for the Association of Computing Machinery’s (ACM) Dissertation Award. Ren’s interests are in digital imaging systems, computer graphics, optics and applied mathematics. He holds an MS in Computer Science and BS in Mathematical and Computational Science from Stanford University.

COBA Holiday Party

Since this is the last COBA meeting of the year, we will be celebrating the end of 2006 with refreshments, snacks, and hearty conversation! I’ll be bringing some snacks and drinks to the party, but COBA members are encouraged to bring additional items to the celebration.

I’ll be showing a slideshow retrospective of the past year of COBA, and we will discuss topics for next year’s slate of meetings.
