Sun prints

 Sunprint Doily 1© Karen Thiessen 2011
Summertime is perfect for making cyanotypes. I bought a Sunprint kit, gathered some objects and let the sun do its thing. Through experimentation I discovered the ideal time of day to do the sun prints. Flat objects print well regardless of the angle of the sun, but to avoid distortion three-dimensional objects print best between 11:30 am and 1 pm when the sun is highest in the sky. The doily that I used for this print was very thin and allowed some light to pass through its fibres, thus resulting in a subtle print. Opaque objects like keys give a high contrast print. The kit that I purchased is geared towards children so the paper quality is poor and curls when rinsed, but is fine for experimentation and scanning the results.
