Blues is a group exhibition curated by Joost Vandebrug that brings together seven pioneering artists from Iran, United States, Belgium, Japan, Sweden, Netherlands and United Kingdom who each explore in their original and uncompromising way the historic photographic process of Cyanotypes.

Cyanotypes were first discovered by Sir John Herschel in 1842 as a simple and low-cost process to produce copies of notes and drawings. Engineers and architects used this process well into the 20th century and the prints were referred to as blue-prints.

Soon after its discovery, it was adopted by artists who were captivated by the rich blue shades of the technique. Most notably, the photographer Anna Atkins. Her book with cyanotypes was the first to be photographically printed and illustrated. Anna Atkins (1799 –1871) was also considered the first female photographer.
