The Djeco Marine Life Cyanotype creative set offers an easy introduction to the traditional photographic printing technique of blue printing. Opaque sea motifs are placed on special light-sensitive paper and then exposed to sunlight. After a subsequent bath in clear water, the outlines emerge as white silhouettes against a deep blue background. Without any chemical mixtures, artistic underwater scenes with turtles, fish and corals are created. The four included felt-tip pens make it possible to add colorful accents to the finished prints and create individual works of art.
