Invented in 1834, Salted Paper Printing was Fox Talbot s original printing technique. It s a simple idea. Paper is soaked with weak salt solution, then silver nitrate is brushed on, and the result is silver chloride. Finished prints have a beautiful delicacy in the lighter tones, but slightly lack in detail overall. Images are contact printed onto art paper sized with starch and then rinsed and given a final wash in several changes of water. The final colour is normally reddish-brown, but by toning with gold a wider range of hues can be created, from reddish-brown to blue- or purple-brown. This also makes the image more permanent.ephotozine
The earliest form of silver halide printing paper developed by William Henry Fox Talbot around 1834. Talbot used paper soaked in salt; this was dried and then brushed with silver nitrate before being exposed and subsequently fixed with a concentrated salt solution or, later, sodium thiosulphate ( hypo ).
