Hi All,

Have just tried Agfa Viradon to try and brown tone my photograph to
make it look like an old picture
as it was taken on an old camera.
The paper used was Ilford multigrade 1V RC size 16" x 12" well washed.
The instructions said dilute at 50 -1 and immerse print for 2 to 10
minuets.
After 20 minuets nothing had happened so I increased the strenght to
1-25.
After 45 minuets still nothing had happened to the print, but the
viradon went all "murky"

Could someone please explain why my print wouldn't tone, also I tried
to tone in some sepia after but it
wouldn't sepia either. Why?????????

Thanks in advance


Some papers don't tone very well but you should have gotten some
color change. Two versions of Viradon were made: The older one was a
combination of selenium and polysulfide similar to Kodak Polytoner and
the later one was sulfide only similar to Kodak Brown Toner. The
polysulfide toner works very slowly unless heated. You might try heating
the toner to about 120F. After toning the print should be treated in a
bath of sodium sulfite to stop the toning and get rid of the yellow
stain. I've found that Kodak Hypo Clearing Agent works fine. I think
this has been discontinued but Ilford's hypo remover should work. I use
the clearing agent at normal working strength.
Polysulfide toner has the virtue of toning all densities at the same
rate so will provide considerable image protection even when only
partial toning has been done.
It has the peculiar property of toning _faster_ when diluted or
partly exhausted and if too weak can leave a peach-colored stain which
is very difficult to remove.
What kind of Sepia toner did you try?

Hi many thanks for the reply, I used fotospeed sepia toner.
I'll try it with my dishwarmer under the tray.

There are several type of "sepia" toner. The one usually called this
is a two step, bleach and redevelop, toner. Some newer papers are very
hard to bleach. If this is the problem you are having you may have to try
mixing your own toner. Kodak was selling Sepia Toner II specifically for
newer papers but I think its been discontinued along with nearly all Kodak
chemicals. Other sepia toners are one-step. The polysulfide type like
Viradon, is one, others have to be mixed yourself. There are many
variations of these but the formulas for Kodak and Ansco or AGFA are
reliable. Google should find formulas or post here and I will send some.
Note that all sulfiding toners smell from hydrogen sulfide (rotten egg
odor) and are best used outdoors.
