The Foma Fomatol PW (W24) Warm-Tone is a specially formulated black and white paper developer in powder form. Fomatol PW contains no Hydroquinone (HQ). It is designed specifically for the manual processing of the Fomatone-line photographic papers, and also works for Fomabrom, Fomaspeed / Fomaspeed Variant III, Fomagraphic and Fomalux. Fomatol PW features slower developing activity and a warm image tone. The developing capacity of this package is 21.5 - 32.3 sq ft (2.0 - 3.0 sq m) of Fomatone photographic paper (about 50 - 75 8.0 x 10" / 20.3 x 25.4 cm sheets).
Developing time at 60 - 68° F (15.6 - 20° C) for standard and Fomatone warmtone resin-coated (RC) and fiber-based papers is 2.0 - 3.0 min (undiluted). In a solution of 1:1 dilution, developing time increases to 4.0 - 6.0 min, and it goes up to 8.0 - 12 min when dilution reaches 1:3. For non-warmtone fiber base paper (Fomabrom), developing time is 3.0 - 4.0 min (undiluted). For non-warmtone resin-coated (RC) paper (Fomaspeed, Fomaspeed Variant III, Fomagraphic and Fomalux), developing time is 2.0 - 3.0 min (undiluted).
Dissolve the contents of the larger and then the smaller bag in 3 cups (700 ml) of warm water at 104° F (40° C) and then add water until the total volume equals 4.2 cups (1 liter). Fomatol PW yields results similar to those produced by the Harman Warmtone Paper Developer.
