PhotoTechEDU Day 12: High Dynamic Range Image Capture

Google Tech Talks April 11, 2007 ABSTRACT Although digital imaging has been around for nearly 40 years, the past decade has seen the nearly complete replacement of analog film by digital sensors, most of which capture only a tenth the dynamic range of the black and white film Ansel Adams worked with 80 years ago. Using multiple exposure techniques (or advanced sensors), it is in fact possible to turn this around and capture ten times the range of film, equalling or surpassing the capacity of human vision. Greg will introduce some of the concepts and present a few details of HDR imaging in the context of digital photography, and demonstrate interactive software he has developed to assist in the...
