Silver Nitrate Tips

Testing your distilled water for Salt Paper or VDB prints

Applying Sensitizer to Paper

Any solution containing silver nitrate should only be applied in a dim lit room without any kind of fluorescent light.

Sizing Paper with Gelatin

  1. Use gelatin in the salt solution to bring sizing to print which in turn give finer and more sharper results.
  2. The gelatin should be completely be dissolved. Apply the solution onto a good quality watercolor paper and let it dry.
  3. Now you’re ready to print.

For other sizing options such as arrow root – check out Jill Enfield’s page on alternative photography.

Hot or Cold ? – Papers

Taken from Water Color Affair

I currently use a Hot Press – ‘Daler and Rowney Sytem 3 Arclyic paper’ which I find robust to use and works well with VDB and Cyanotype. To buy papers in Europe/UK

Printing Out Process

Print out in the shadow not in direct sunlight for the best details in highlights and shadow for VDB and salt paper prints.

Humidity

Vandyke, like kallitype and platinum/palladium, gives richer tones if coating and drying is carried out in conditions of high humidity, at least 50% RH in Sandy King’s experience. If the room conditions cannot be raised to an acceptable RH the paper can be moistened before sensitising by holding it over a kettle of boiling water for a couple of minutes.

Before Fixing for Salt Paper / VDB

Hypo Clear Solution

Use Hypo Clear before fixing the a VDB or salt paper print. Hypo Clear is simply sodium sulfite. To finally finish the print add 20g of sodium sulfite per litre of water.

Why ? Removes leftover hypo in your prints and negs which can damage them over time.

How ?
Hype Clear Agent aids in the archival process, based upon ion exchange: ions absorbed onto a solid film or paper can be replaced by ions of a solution such as those found in the Hypo Clear solution. The net effect is that the absorbed thiosulfate ions of the hypo (difficult to remove by a water wash) are replaced by sulfite ions (readily removed by a water wash). Hypo Clear does not decrease the total number of ions absorbed on the paper, it merely exchanges those ions originally on the film or paper with those of the Hypo Clear. Washing after the use of Hypo Clear is imperative.

Fix and 30 minutes washing.

Note: for film emulsions which are thin is less likely that the hypo is absorb into the substrate. Hence it’s not required for these kind of media.

Hypo clear can be sent down the drain without any worries.
