In this work, the artist uses the cyanotype technique invented in the 19th century, based on the use of iron salts sensitive to light, that produce a blue image called cyan or Prussian blue. This practice calls for manual action. The product is deposited on the paper using a brush. This image plays with the overprint of two vegetal patterns found in Arles: the branches of a resinous shrub in a public park and the mimosas branches in a private garden. It is expressed using natural tanning technique that blackens the original blue, and colorized with dry pastel. The so-called “direct blackening” process is such that the print has the size of the negative. This cannot be enlarged, hence the digital high resolution reproduction of the original.
