Cyanotype

Cyanotype - tint - shade - tone - hue

 

Cyanotype is a photographic printing process that produces images in a distinctive blue color. It's a simple and historic photographic technique where light-sensitive chemicals are applied to a surface, usually paper, and then exposed to UV light, typically sunlight. The chemicals react to light exposure, resulting in a blue and white color palette. Cyanotype colors are characterized by their deep blue tones, which give the images a unique and ethereal quality. This process was often used for creating blueprints and early photographic experimentation.
