The works shown here are made with cyanotype.
A cyanotype is the result of a photographic process that produces a cyan-blue print (blueprint) after development. Rudolf sometimes reworks these with watercolor paint so that it is possible to use other colours. Each cyanotype is unique. In order to be able to work in editions, Rudolf has art prints made of this.
The piezography or giclée art print is a contemporary digital printing technique that meets the highest demands placed on graphics by artists, museums and art collectors.
the artwork is signed, numbered and provided with a passe partout.
