In computer graphics and photography, high dynamic range imaging (HDRI) is a set of techniques that allow a far greater dynamic range of exposures (i.e. a large difference between light and dark areas) than normal digital imaging techniques. The intention of HDRI is to accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to the deepest shadows.
I know I was frustrated recently while on my honeymoon trying to take a picture of my wife outside of the Sydney Opera House as I faced the Harbor Bridge. As the flash went off, I was not able to accurately the bridge in the background with my wife in the foreground. Annoying. Anyway, I’m glad to see that it might be within my reach (financially) in the near future.
