Foma Fomatol PW (W24) Warmtone?is a specially formulated black and white paper developer in powder form. Fomatol PW contains no hydroquinone (HQ) and iis designed specifically for the manual processing of the Fomatone-line photographic papers, but?also works with the?Fomabrom and Fomaspeed Variant photographic papers. Fomatol PW features slower developing activity and a warm image tone. The developing capacity of this package is 2-3 sq m) of Fomatone photographic paper (about 50-75 sheets size 8×10″ / 20.3 x 25.4 cm).
Developing time at 15 – 20? C for standard and Fomatone?warmtone?resin-coated (RC) and fiber-based papers is 2 to 3 minutes (undiluted). In a solution of 1:1 dilution, developing time increases to 4 – 6 min, and it goes up to 8 – 12 min when dilution reaches 1:3. For?non-warmtone fiber-based papers (Fomabrom), developing time is 3 – 4 min (undiluted). For non-warmtone resin-coated (RC) papers (Fomaspeed Variant III), developing time is 2 – 3 min (undiluted).
Dissolve the contents of the larger and then the smaller bag 700 ml of warm water at 40? C and then add water until the total volume equals 1 liter. Fomatol PW yields results similar to those produced by the Harman Warmtone Paper Developer.
