I recently purchased Photomatix which is software that is used to create high dynamic range imagery. High Dynamic Range or HDR is a set of techniques that allow a greater dynamic range of luminances between light and dark areas of a scene than normal digital imaging techniques or photographic prints. This wider dynamic range allows HDR images to more accurately represent the wide range of intensity levels found in real scenes ranging from direct sunlight to faint starlight. Hdr Soft makes Photomatix as a stand alone version as well as a plugin for photoshop, adobe lightroom, and apple aperture.
