HDRPhotos.org provides HDR photographer enthuisasts with a place to learn, study and discuss HDR photography. High dynamic range imaging (HDRI or just HDR) is a photography technique that lets the photo have a much greater dynamic range of luminances between the lightest and darkest areas of an image than standard digital imaging does. The wider dynamic range allows HDR images to include much more details with the wide range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.
