On the last Saturday of September, the TinyGallery in Brussels participates in the world cyanotype day. Organized since 2015, this day brings together fans of this ancient technique worldwide. Leaving from the United States, the idea is to make a large collection bringing together all the creations of artists who love these images with so deep Prussian blue. This year, in particular, the online version will make it possible to link all the creations around the “interconnected” theme. Symbolic, these images of salts and paper will bear witness to the work of ever more numerous amateurs.
