BVD Process: Step One, Cyanotype
Cyanotypes are a beautiful blue mixture of painting and photography. It is one of photography's oldest processes, where ammonium iron(III) citrate and potassium ferricyanide are mixed in equal parts and painted onto a paper and exposed under the sun or UV box.
- cyanotype formula A and B
- watercolor paper
- droppers (marked A and B)
- plastic cups
- cup with water for the brushes
Step One: Prep Yo' Paper/Yo Gloves
Dim the lights.
Moisten your brush in the cup of water just enough that it won't soak up the cyanotype fluid.
Cut the pieces of watercolor paper down to the size you'd like them to be, tape the sides down if you want a clean line.
Step Two: Mix the formula
Put on your Gloves!
Make sure that you marked the droppers so the chemicals aren't mixed by accident in the bottle. Using the droppers, measure and mix equal parts of formula A and B in a cup.
You don't need much. 40 drops of each will cover an 8 x10 inch surface area.
After mixing the formulas, dump the cup out on the paper and brush it around.
Let the paper dry in the dark or dim room. When the paper finishes drying, place your paper.
Step Five: Gather Materials and Place Negative or Materials on the Paper.
Step Four: Exposure
Expose the plates in strong sunlight or UV box until satisfied or 15-20 minutes.The longer the exposure goes, the deeper the blue and the more stark the contrast becomes.
Step 5: Rinse for at least 20 Minutes
Step 6: Taaa-Daaa!
Allow to dry. Your cyanotypes are done.
