Fotospeed Cyanotype Sensitizer - 50ml

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.

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.

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.
