Ilford Harman Warmtone Developer is a liquid concentrate hydroquinone developer suitable for the dish/tray developing of all black and white photographic papers both resin coated (RC) and traditional fibre based (FB). It is used at a dilution of 1+9.
Warmtone developer is clean working, has excellent keeping properties and gives a warmer image tone to most papers. Warmtone developer is designed for use at ambient room temperatures, nominally 20°C/68°F.
Note: Ilford does not recommend its use for high temperature or machine processing applications. It is NOT suitable for developing films.
Warmtone developer is designed for use at ambient room temperatures, nominally 20°C/68°F
Working strength developer left in an open dish should not be kept for more than one working day - If stored in a tightly capped bottle it may last up to 24 hr
The recommended developing temperature is 20°C (68°F) +/- 1°C (2°F); Slightly lower temperatures can be used but development would need to be extended slightly; Slightly higher temperatures can also be used but development times would need to be reduced
