During summer vacation, GREEN SCREEN offers adolescents between 12 and 18 years of age the possibility of attending the popular five day youth film camp in the wilderness park Eekholt near Hamburg. Under professional guidance by Heinz Sielmann's former cinematographer Dieter Hoese and with the help of media educators, the young participants learn about the ups and downs of wildlife filmmaking, for example how to achieve good pictures despite heavy rainfall and bad lighting conditions.
The young filmmakers learn first hand just how much hard work lies in the making of a movie, but of course the main focus is on the fun in creating a film and on learning that a good film depends on good teamwork. Additionally, the staff of the nature education centre provides important background information about the different plant and animal species. The often impressive results of the workshop are screened and discussed with attending professionals during "filmmaker consultation hours" at the festival.
