Cyanotyping (deep blue sun printing) has been around since 1842.
An owl fancier asked if I could produce an owl pen in a leafy setting with an old fashioned look; steps:
Photographed a rescued Horned Owl (successfully released back into the wild on the next day).
Composited the owl picture with a picture of leaves (creating a leafy setting).
Grayscaled, then inverted the image and laser printed a negative film transparency.
Cyanotyped (sunprinted) the image onto photo-sensitized fabric (used a mixture of ferric ammonium citrate and potassium ferricyanide VERY CAREFULLY prepared outside with proper precautions); sandwich made of plate glass/negative transparency/fabric/black matte board; 15 minutes exposure at 3PM, bright sun.
Rinsed, and then developed the image by oxidation in a dilute bath of peroxide.
Air dried the fabric, then ModPodge glued it onto the brass tubes.
Hand tinted the image with pearlescent inks.
Tube-in casted the upper and lower pen barrels in PR flecked with fine metal gilding flakes, cured x 3 days.
Lathe-turned, finished, and assembled as usual:
Fun process - should open some new creative possibilities.
Have a fine weekend - Bob
