Create blueprints using an analog photographic process discovered in 1842. No darkroom needed, just this kit and some sunlight! With the components in this kit, you can transform watercolor paper postcards into photo paper: making them sensitive to UV light. Create blueprints from natural materials and objects. Just a moment in the sun and you'll see them change color! With this kit, you can mix and apply the photographic solutions yourself, enough for the postcards in the kit and a little extra to experiment further on your own. Want to blueprint photos? Then you'll need transparent sheets. These are included in our larger DIY Paper kit or can be purchased separately.
