Re: Bleaching for a lith effect.

[Graham <cmm@xxxxxxxxxxxx>]

Sorry, I made a mistake in the URL below, I have corrected it and
it now should work just fine.




Most interesting......

I have played around with Lith for a while and haven't really hit upon a
favourite recipe yet.

However, I have also taken a side track into bleach/redevelopment. I just
tried bleaching with a ferri/bromide bleach and redevelopment/tone in 
selenium and liked the effect quite a lot.  I use Ilford Warmtone RC paper
developed in Ilford multigrade developer.

a sample is at:   http://timmins.vianet.on.ca/pages/cmm/lith001.html

My next experiment will be to try it with prints of different contrast 
grades from 0 to 5; I suspect that I may get more interesting results
from the prints on the lower contrast grades.  I also am going to try
gold toning after selenium as well as using Viradon as a partial tone
before selenium and after selenium. The problem with all this is that
there are too many combinations and permutations.  I would never have
tried bleaching and redevelop/tone in selenium had I not seen it made
reference to Tim Rudman's book.

I mix my own Ferri / Bromide bleach and you don't need a weigh scale.
Get a good set of stainless or plastic measuring spoons.

Potassium Ferricyanide  3 tablespoons (approx 48g)
Potassium Bromide       7 teaspoons   (approx 45g)
start with 400 ml water at about 100 degrees F and top off to 500ml 
after the chemicals are disovled.

The "classic" 10% mixtures would 50g of each in 500ml but the above is
close enough.  I then dilute at about 20ml stock solution to 1 litre of
water to make my bleach.  You could use 10ml or 30ml if you wished of course,
the weaker bleach works slower and you will more control.

You could also just mix up solutions of just Ferri and just bromide, use
10ml of each to a litre of water that way you wouldn't have to keep separate
bottle of 10% bromide and / or Ferri for other uses.

cheers, Graham

Are the shadows there for me to find, or placed there by my searching mind.
When I reach and find them gone, was I right or was I wrong?
