This Cyanotype solution is a replacement for the Cyanotype sensitizer supplied in the original Fotospeed Cyanotype Kit. It is in a single working solution, based on Ammonium Ferric Oxalate which gives a good blue which will not wash out and is twice as sensitive to ultra violet lights as the historic alternative process version.


Development, as in all Cyanotype processes is simply done in water. A citric acid (Stop bath) 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.

Customer Reviews (4.2 / 5 · 5 reviews)

Mia ★★★★★

Mixing this single working solution under amber light was far less messy than dealing with separate chemicals. My first test print came out with deep, rich Prussian blue tones after just 10 minutes in the sun.

Grace ★★★★★

Mixed this up last weekend and got beautiful, rich Prussian blue tones on the first try—no measuring or extra steps needed. The solution stays stable for weeks in the fridge, which makes it easy to use for multiple sessions.

Victoria ★★★★☆

The single working solution is a real time-saver compared to mixing two parts, and my first prints came out with a nice deep blue. Only gripe is the 50ml bottle goes fast if you're coating larger sheets, so I'd already be ordering a second one.
