Abstract
I present a revised approach to flash-exposure high dynamic range (HDR) imaging and demonstrate two applications of this image representation. The first application enables the creation of realistic ‘virtual photographs’ for arbitrary flash-exposure settings, based on a single flash-exposure HDR image. The second application is a novel tone mapping operator for flash-exposure HDR images based on the idea of an ‘intelligent flash’. It compensates for the depth-related brightness fall-off occurring in flash photographs by taking the ambient illumination into account.
