The City of Amsterdam is experimenting with using natural-media techniques and the public space to engage with the public. Amsterdam is one of the first cities to officially allow the use of natural-media for their own communication purposes as long as the materials used to produce the prints are sustainable, high qualities standards of the city are met and the prints are removed after an agreed upon period of time.
Natural media techniques are magical. One of my favorites techniques is reverse graffiti also known as green graffiti, clean advertising, grime writing and many other names. There is something about cleaning an image or a communication message out of the dirt using only a template, clean water and a power washer that is very appealing. While producing works companies can capture amazing content to use as part of the content marketing strategies.
