Sun Snap sun-printing utilizes the cyanotype process, a technique that artists have employed since its development in the 19th century. Objects that block the sun's light will show up in white, with the rest of the paper turning a vibrant Prussian Blue. These larger sheets give you more space to create detailed compositions with multiple objects, bigger botanical specimens, or more complex arrangements. This kit includes 10 sheets of light-sensitive paper. Place any object on the paper, then put it in the sun for a few minutes to capture stunning blue and white impressions with plenty of room for creative experimentation.
