Cyanotypes

Cyanotype processes create a blue hue to the image with an interesting translucent effect on the object. Cyanotypes are typically found in blue-prints for architecture so plans for building becomes clearer. Many photographers have used cyanotypes as a development from photograms such as Anna Atkins, who captured plants for biological scientific purposes. The process can reveal more about an object, and the shadows are a lot clearer than photograms.

What do I need?

– Ammonium Ferric Citrate

– Distilled water

– Thick card

– Potassium Ferricyanide

– Brush

How do I make it?

1 / Create solution (65g of Ammonium Ferric Citrate with 250ml of distilled water; and mix 23g of Potassium Ferricyanide, with 250ml of distilled water)

2 / Then paint the solution onto the thick card with an equal coating

3 / Place the object you want to exposure on top of the sheet

4 / Put everything steadily under a UV light source with the coated side on the light source (Light bed 20/30 minutes or sun 15minutes)

5 / Wash off the yellow tone form the print under cold water for 10 minutes

Then you should have a nice blue toned print with the objects printed in white.
