Tanaka Direct Dye Shop｜Cyanotype Kit

Cyanotype is one of the world's oldest photographic techniques, characterized by its blue-toned images. It's a method that uses the power of light and the chemical reaction of iron salts to fix images in blue, commonly known as "blueprints" or "sun prints." In the past, it was widely used for architectural and design drawings, often referred to as "blue-lined drawings." The expressions "blueprint" and "to draw a blueprint" for future dreams and plans originate from the color and use of cyanotype. This kit allows you to safely experience cyanotype, the world's oldest photographic technique, at home. Please enjoy the process of how it reacts to light and turns blue.
