(Because we all lose paper copies.)
Salt Printing Method:
-Coat the paper generously with Salt Sensitizing Solution (add 1 drop potassium for more contrast)
At this point, the paper is not light sensitive, and can be stored.
-Coat paper with Silver Nitrate Solution. *This solution is dangerous. It is poisonous if swallowed, and can lead to blindness if it gets in your eyes.*
At this point the paper is fairly light sensitive, and should be stored for shorter amounts of time.
-Expose the paper in the same manner as a Cyanotype or Vandyke. It will darken visibly within the first minute. It is usually a good idea to wait at least three minutes. The image will darken and the yellow stain will fade during the post-exposure process, so look for exposure to be ½ or so as dark as the final product.
-Wash in rinse and fix as you would a Vandyke.
