Gold, Platinum & Palladium Tones For Silver Gelatin?

[menglert]

Hello,

I'm looking for some gold, platinum, and palladium toner formulas for silver gelatin papers. I have the common gold formulas from Rudman's book, but does anyone have resources for other formulas?

Thanks,
Martin

Hi Martin,

Dictionary of Photography (19th Ed.); Illife Books Ltd, London; Sowerby, A.L.M. (ed.); 1961, pp 657-658 has a formula for Platinum toning Printing Out Papers. I guess this would work on D.O.P.s, but I've been wrong before. Comments in brackets mine:

"This process gives very beautiful brown colours. First treat the prints in a 5 per cent solution of common salt (sodium chloride), rinse well and tone in:

Potassium chloroplatinite - 0.6 grammes;
Citric Acid - 8 grammes;
Water to - 880 c.c.

Wash thoroughly before fixing." (P.O.P. was traditionally toned before fixing.)

The text also lists two formulae for gold toning on p.654:

"The Ilford IT.5 formula is:

A. Thiocarbamide (Thiourea) 14 grammes;
Water to 1000 c.c.

B. Citric Acid (crystals) 14 grammes;
Water to 1000 c.c.

C. Gold Chloride 6 grammes;
Water to 1000 c.c.

For use, take 1 part each of A, B and C, and add to 10 parts of water. Chlorobromide prints benerally tone in 10 minutes or less; bromide prints take longer. Keep prints moving during toning and wash well afterwards.

Applied to a print already toned by any of the sulphide methods, gold toning gives a brilliant red-chalk colour. The Ilford IT.4 toner is:

Ammonium thiocyanate 20 grammes;
Gold chloride 1 gramme;
Water to 1000 c.c.

For a full red tone, about 10 minutes is normally needed. After toning, refix in 10 per cent hypo and wash fully".

Hope that's useful to you, have fun.

There is no way I know of using platinum or palladium to tone developing-out paper. The formulas that exist are for albumen, POP etc. I've experimented a bit with palladium and platinum salts, and had no success. Gold is another matter. In addition to the formula above, this works great:

Ammonium thiocyanate 50-100g
Gold chloride 0.1-1 g
1L water

A lot of useful information and formulae for old style printing here:

Some of my friends in the New England Large Format Photography Collective have made some beautiful gelatin silver prints toned in potassium tetrachloroplatinate. It can certainly be done, and often to stunning effect.

Would you happen to have a formula, or can you get one? Thanks!

Thank you everyone for the feedback.

What sort of effect does one get with such toners? Warm? Cool? Any details?

Thanks,

Warm. I'm very short on details. I've only seen the prints. Try contacting Steve Sherman. steve@steve-sherman.com
