Camera obscura is a dark room with a hole in one of the walls. On the opposite side, a reduced and upside down image of the surroundings is created. If there is silver bromide-coated photo paper there, this image can be recorded, it is then called a pinhole camera - the simplest camera.
Already 1000 years ago such a camera was used by the arab Alhazen for observing solar eclipse. Aristotle recognized the principle, but it was Johannes Kepler, who published 1604 the work "Astronomiae Pars Optica". He fully explains the functionality of the "Camera Obscura".
The project "EDITION - Weil der Stadt 100/2015", which starts on 28 May in the Wendelinskapelle, is also a homage to the famous astronomer. There are exactly one hundred pinhole cameras for one hundred photographs of this special edition. Whoever acquires such a camera can create a long-term exposed picture of any object in Weil der Stadt.
The exposed original will then be digitalized by P. Zajfert and will be added to the edition Some of Weil der Stadt's views will be shown in the chapel in large format. The finissage with all the works can be seen on October 2015 in the Badtorstr. 18 Art Drawings by K. Fabelova in Weil der Stadt.
