Re: Réf. : Re: Carbon Color

I see, but I was actually referring to the following
page:

You say ammonia + tannic acid... Then I guess the
"mauve" example is toned and/or bleached shorter than
the "rougêatre" example... Is it so?

I also did the ammonia - tannic acid toning (I toned
fully; bleached around 3-4 mins and toned for at least
10 mins, see the tech. details in the following
pages). Here is my result:

Original print:

The same print after toning:

I did the scans very carefully; I tried to make them
present the prints as much as possible.

As you can see my toning experiment went quite
differently (probably due to the different paper I had
used - what do you think?). Your examples are much
more lilac or reddish than what I got. I also would
like to make these reddish - lilac cyanotypes (BTW, is
there any method to make a cyanotype resembling a
chrysotype? These are lovely but way beyond my
limits...) Any suggestions? Would like to hear tips
for black, red, mauve/lilac cyanotypes (please note
that longevity is important issue to me)...

TIA to all.

Loris.
