High dynamic range photography is a process in which multiple exposures are captured, aligned and merged to generate a single image that enables a much wider range of colors, highlights, and shadows. HDR techniques are typically used to enhance landscape, architectural, nighttime, and artistic photography. New HDR Efex Pro overcomes limitations in other software tools with a revolutionary all-in-one approach that enables both realistic and artistic effects to be applied within a single tool. Color, contrast, and vignette controls enable photographers to further enhance their images to create amazing results. This feature enables photographers to reprocess images in which either an exposure series was not previously shot or for subject matter that does not lend itself to multiple exposures.
