My name is Karsten Hein. I’m a documentary filmmaker, writer and photographer. Since 2011 I’m working with blind people on photo projects. In these projects we learned that the dialogue between Blind and Sighted about pictures is knowledge-enhancing for both sides. For this dialogue picture descriptions are the central translation tool. For me, Wikipedia embodies the good side of the Internet. And as far as one can say as a contemporary, it is already one of the great achievements of humanity. I am grateful to everyone who has contributed and is contributing to it.
