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.
The XCF file format is the native image format used by GIMP (GNU Image Manipulation Program), a free and open-source raster graphics editor used for image editing, free-form drawing, converting between different image formats, and more specialized tasks. XCF stands for eXperimental Computing Facility, which was the name of the lab where GIMP was originally developed. XCF files are designed to store all the information that GIMP needs to accurately render an image.
