Description
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.
This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. Group 3 eliminates redundant data during compression in order to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can lead to a significant loss of image quality.
