The subject of this final thesis is cyanotype, one of the oldest photographic techniques used to obtain photograms of the characteristic Prussian blue colour. By studying relevant scientific literature, the thesis familiarizes us with the discovery of cyanotypes, the process and technique of making cyanotypes, and the creative possibilities of their application. The first part of the thesis presents a brief historical overview and description of the cyanotype technique through a historical account of the development of photography and a fascinating historical overview of the characteristic Prussian blue colour. The paper explains the term and describes the process of making a blue photogram, from the composition and preparation of chemicals into a photosensitive emulsion, preparation of the base and negative, to the process of lighting, developing and drying, and fixing the print. The second part of this thesis provides an overview of female and male artists who used the cyanotype technique in their creative work and introduced it to the world of art by studying their distinctive ways of performing cyanotypes and motifs in their creative work. The work aims to investigate and observe the significance of this simple, cheap, and, above all, non-toxic blue print technique in contemporary art and the social context, as well as its applicability to textiles.
