Fotospeed Cyanotype Sensitiser 50ml

The Cyanotype sensitiser supplied as solution only or as part of the Cyanotype Kit is a single working solution and is an updated version of the original process. This formula uses Ammonium FerricOxalate to give a good blue which does not wash out and is twice as sensitive to UV as the traditional version. Development is in water. A citric acid solution can be used to manipulate contrast. All images are made by the contact system, where the image depends on a negative of the appropriate size or the placement of an object on the sensitised material.

Nicholas M. ★★★★★

After mixing two test prints by the book, the single-solution formula processed cleaner than any two-part kit I’ve tried before. The deep Prussian blue came out perfectly even on just the third wash.

Alexander ★★★★★

Used it straight out of the bottle as a single working solution, which saved me the hassle of mixing two parts. The prints came out a deep, even blue with no patchiness, and the liquid stayed good for a couple of weeks in a sealed container.

Madison Y. ★★★★★

The solution consistently gives me rich, deep Prussian blue tones on the first try — no mixing required. I've used it with cold-pressed watercolor paper and the detail is sharp. Still on my first 50ml bottle after a dozen prints.
