The large snowy owl cyanotype is printed on heavy French handmade Arches watercolor paper. The fibers really absorb the photo solution resulting in a very deep prussian blue. The printing process is unique as well since the paper is hand coated, exposed and washed individually. Measures: 34" x 57". We can ship this item rolled on a very wide 8" tube diameter for safety and easy unrolling. Below is a detailed description of the process:

The cyanotype process was developed by scientist and astronomer John
Herschel in 1842. The process was created only three years after
photography was invented. This process instead of using silver like
typical photography uses iron. The iron ‘salt’ solutions are combined
and coated on watercolor paper in a dark room and allowed to dry. When
a negative or plant material is placed on the paper it becomes a film
negative. The uncovered areas are exposed to UV light and cause a
reaction to the iron solution reducing it chemically to a deep
Prussian blue. The print is then washed and the covered dark areas on
the negative create the white and the exposed become deep blue. It is
a simple and natural process.
