Raster image or digital photo saved in HDRsoft's High Dynamic Range (HDR) image format; used for enhancing the color and brightness range of a digital image; can be processed to fix dark shadows or washed out areas of a picture.

HDR software can also composite multiple photos with different exposures to create a single image with a full and evenly distributed range of color.

HDR files are also known as Radiance HDR or HDRI files.
