Sun Sensitive Paper Sun Sensitive Paper is coated with light-sensitive chemicals, which react to light waves and particles when exposed to light. Place leaves, flowers, coins, and other objects on this paper. A perfect white image on a blue background will result. Linking art with science, this process can create amazing effects. Method: Sun Sensitive Paper Step One Always choose a day and time where you can see your own shadow to avoid paper from not exposing. Otherwise use a UV Lamp. Step Two Place objects onto the Sun Sensitive Paper indoors. Cover with Acetate so objects don't move. Whilst transporting paper outside cover with a dark sheet. Step Three Expose paper to UV light for 3–7 mins. The results depend on the density of the objects or image, as well as how long it is exposed. Step Four Rinse the paper in a waterbath to “fix” image. Paper will darken as it dries. Step Five The blocked light has turned to white while the paper has remained blue. Exploration:Sun Sensitive Paper Experiment with Height Lace standing upright, creates a great 3D effect. Photographic Negatives Lay down 35mm film negatives onto the sun sensitive paper for photographic results. Srunched Paper Scrunched up paper plays with the sun's shadows.
