is an increase in maximum black. The shadows turn colder. In a dilution
of 1+30 the highlights start shifting to warmer hues after around
30 seconds. Later in progress this hue turns towards red-brown or
yellow-brown. Simultaneously the shadows become warmer. If you want
intensive red-yellow highlights, you can bleach them a little bit
before you start toning. Even if your bleacher is highly diluted,
times between 15 and 30 seconds can already be sufficient.
increase maximum black, you should use a strong working solution
(1+10 to 1+15) and tone for only a short time. You will also get
a colder image tone. To protect the image silver from environmental
stresses, toner dilutions of between 1+100 and 1+200 and toning times
of 3 to 6 minutes are sufficient.
Working solutions of up to
1+30 can be stored for a couple of weeks. Discard very highly diluted
working solutions after use.
When you achieved the desired
tone rinse the print in running water. The toner contains sodium-sulphur.
