Egill Ibsen shows us how cyanotypes can be painted with acrylics to get a spectacular result.
I first prepare a classic cyanotype either with standard or digital negative.
Usually I only dip it in 3% Hydroxide Peroxide for the added deep blue but sometimes I use Acetic acid as well to manipulate the print. Try to avoid pushing the brushes to hard or you will risk lifting the cyanotype layer of the paper.
After drying the print thoroughly I prepare the acyrilc paint. Some aerias are
painted thickly f.ex. the “tree”.
Other areas are painted with many layers of thin washes.
I like to paint these thin washes quite quickly and then I even them out with a mop brush. After every application the print needs to dry otherwise one risks muddying the painting.
Sometimes many layers are needed to get the desired effect.
The rest of the print is painted with different types of brushes and washes.
I use hog hair brushes to ruffle up the paper for added texture and effects.
To touch up the cyanotype layer or to deepen the shadows I find the Payne´s
Gray color to do the best job.
