    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

  2. 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.

  4. 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.
