Vandyke photography- alternative photograph processing.The Van Dyke print is developed in plain running water, which completes the chemical changes initiated by exposure to UV light. It is then fixed in a quite dilute (3-5%) solution of standard print fixer for a short time to remove any insoluble silver compounds which might darken with continued exposure to light. Finally, it is rigorously rinsed, hypo-cleared, and washed to remove all traces of the hypo fixer.

Kalli Print-Kallitype printing follows similar procedures and uses many of the same chemicals as Platinum and Palladium Printing. Kallitype is a great process for students and beginners who want to practice their handcoating and printing techniques before moving up to Platinum or Palladium printing.

Instructions

Cyanotypes- is a photographic printing process that gives a cyan-blue print. The process was popular in engineering circles well into the 20th century. The simple and low-cost process enabled them to produce large-scale copies of their work, referred to as blueprints. Two chemicals are used in the process:

• Ammonium iron(III) citrate
• Potassium ferricyanide.
