FOMATONE
Fomatone is a variable contrast paper with a chloro-bromide emulsion system. Fomatone produces extremely warm tones, and may be unique in that it has not yet been reworked to remove trace elements which are beneficial to chloro-bromide characteristics, including good shadow separation, deep blacks, and reactivity to ‘lith’ development. The paper has a warm-white base which complements the image colour. Grade range attainable can extend from about G1 to G4. 
Fomatone can be developed to give a very warm colour using a warm developer such as Ilford Warmtone, or Agfa Neutol WA, especially if it is substantially over-exposed and the development curtailed. 
Overdevelopment can be used to give a cooler image, and to increase the contrast. Fomatone is available in semi-matt and gloss surfaces.
