HDR Photography Photo Gallery. Clive Smith has just published a new set of photos titled HDR PhotographyHigh Dynamic Range photography (HDRI or HDR) is a technique used in photography to reproduce a greater dynamic range of luminosity than possible using standard photographic techniques. HDR images can represent a greater range of luminance levels found in real-world scenes, from direct sunlight to faint nebula. It is often achieved by capturing and then combining different exposures of the same subject matter through a built-for-purpose application. It's not everyone's taste, but I love it!Check out Clive Smith’s portfolio here.
