Negativefeed Cyanotype Kit

Cyanotype is a historic photographic printing process known for its distinctive deep blue tones. Using a simple two-part solution and UV light, it allows you to create striking prints on paper, fabric, and other surfaces.

About

The cyanotype process is one of the oldest photographic techniques, valued for its simplicity and expressive results. Instead of traditional silver-based chemistry, it uses iron compounds that react to UV light to form Prussian blue images.

By combining potassium ferricyanide and ammonium iron citrate, you create a light-sensitive solution that can be applied to a surface. When exposed to sunlight or UV light, the coated areas transform into rich blue tones, while unexposed areas remain light after rinsing with water.

Product details

Potassium Ferricyanide (Solution A)
Potassium ferricyanide is one of the two light-sensitive components used in the cyanotype process. When combined with ammonium iron citrate, it helps form the characteristic deep blue pigment (Prussian blue) upon exposure to UV light. This solution plays a key role in creating the final image.

Ammonium Iron Citrate (Solution B)
Ammonium iron citrate is the primary photosensitive compound in the cyanotype process. It reacts to UV light, and when mixed with potassium ferricyanide, enables the formation of the image. Areas exposed to light will turn blue during development, while unexposed areas remain light.

Development (Water Processing)
Unlike traditional film development, cyanotypes are developed simply by rinsing the exposed material in water. This washes away unexposed chemicals and reveals the final blue image. No additional developer, fixer, or stabilizer is required.
