Baryta

Baryta or barium sulfate (BaSO4) has been traditionally used as a brightener or whitening agent in silver halide photography papers. More recently the term has developed a new meaning thanks in part to marketing efforts of inkjet paper manufacturers. The term is now synonymous with the style of papers which traditionally used Baryta and in general. The newer inkjet papers may or may not utilize Baryta as a whitening agent and care should be used to verify its use. The whiteners longevity in digital papers has not been widely tested as of yet.
