The Photosphere HDR Image Browser

March 12, 2003 - 12:00pm

The speaker will present a user-friendly application for creating and cataloging high dynamic-range images (HDRI). More akin to photographic negatives than standard TIFF or JPEG images, an HDRI has enough latitude to permit re-exposing regions in order to bring out detail in highlights and shadows. Creating an HDRI requires either a specialized camera or a standard camera and multiple exposures of a static scene. In this talk, the speaker will give an overview of the Photosphere application and give a live demo of HDRI creation using a consumer-grade digital camera, which yields a photometric image in CIE XYZ coordinates. Photometric images have uses beyond standard photography, enabling applications in lighting and visibility analysis. In addition, we will demonstrate some of the program's other helpful and unique features for browsing and tracking digital imagery.
