Cyanotypes are known for their luminous shades of Prussian blue. But as beautiful as that shade of blue is, what if it's not the right color for a certain subject or mood? Well, cyanotypes are wonderfully versatile, and it turns out that the colors can be altered by toning the print in different liquids. Some of these are specially formulated chemicals, while others are common liquids found around the house.
Would you believe that one of these is coffee?
After creating original blue-and-white cyanotypes, I then let them soak in a tray of fresh, warm coffee for well over an hour.
When the prints came out of the tray, the blue had morphed into a dark gray, while the cream-colored paper had turned a lovely shade of caramel. Who knew how useful coffee would be for my photography?
