Here is the method I used to recreate a Victorian Salt print at home. At some point I would like to experiment with a calotype but currently I don’t have access to a darkroom. 

EXPOSE YOUR IMAGE 

The image was exposed normally on a Wista 5×4 with a 150mm lens. (Always air on the side of over exposure if you are faced with a choice.)

DEVELOP YOUR FILM 

 but give the development time 50-100% more time than recommended. This is where you need a good exposure, if your over your negatives will end up as window blinds, however if your exposure is good you negative will be higher density and much more useful for most alternative processes. As they require higher contrast.

THE PRINT 

Mix a solution of sodium (sea salt) or Ammonium (photographic grade) Chloride, with clean tap water. Place it in a tray, i find plastic works well and chrome trays will rust very quickly when working with strong salts.

SALTING THE PAPER

There are two ways i have read on salting the paper the first i use, is to leave the paper in the salt water for no more than 5 minutes 

The second is to gently float the paper on the salt without immersing it or soaking it, be sure to mark which side of the paper is salted.

SILVER NITRATE SOLUTION 

Using fresh distilled water pour out 50ml into two clean jars, into the first mix 6 grams of citric acid and into the second 12 grams of Silver nitrate. Silver nitrate will satin any and all organic matter it comes into contact with, but not right away. The problem will “develop” over time. Be sure to wear gloves and work in a well ventilated area. 

Once the two solutions have dissolved mix them together and store in a light tight bottle.

SENSITISING THE PAPER,

Once the salted paper is dry and Under safe light or low light conditions brush the silver nitrate solution onto the areas you will be placing your contact negative, law to dry in a dark place, ready for printing. 

EXPOSURE 

Place your negative emulsion side towards the sensitised side of the paper leaving the negative towards the light, place under glass or in a dedicated printing frame for around 5 minutes under strong UV light, exposure will always vary depending on your negative. 

Once you are happy with your exposure still under low light wash the print for a few minutes, it will go a brown colour but don’t panic.

FIXER 

Once washed place the print in a solution of 10% Sodium Thiosulphate, modern fixers are two aggressive but this will work fine,

WASH 

Wash for between 5 and 40 minutes, hang up to dray and you now have a Victorian salt print 

I purchased my chemicals from either Amazon or Ebay,
