Close to the Spring Equinox students from several schools all around Europe have built pinhole cameras by themselves. The pinhole cameras were made of matt-black cardboard and other simple material using a design scheme that was provided by Sakari Ekko the project coordinator.
The pictures from these observations have now been released and are presented next. The image is copyright of the authors.
