The digital negative is the collective name for methods used by photographers to create negatives on transparency film for the contact printing of alternative photographic techniques. The negatives can also be enlarged using traditional gelatin silver processes, though this is usually reserved for negatives of 4x5" or larger due to quality limitations imposed by printer technology.^{[citation needed]} This set of techniques is separate from the Digital negative (DNG) file format, although this format may be used to create digital negative transparencies.
