Julius von Bismarck created a device that allows you to physically manipulate a landscape while it is being photographed. This ingenious device allows you to project an image, a sentence or a mark of some sorts everytime someone takes a photograph using a flash, altering the scenery or the objects that the unsuspecting tourist might be photographing.
The way this is done is actually quite simple, taking advantage of a fairly old technology used by photographers. Before, when you took a photograph with several flashes, you had to guarantee that they would all flash at the same time - or very closely together - lighting the object you want to photograph in various angles at the same time.
One of the techniques consisted of connecting a shooting cable between the camera and the various flashes, assuring they were triggered at the same time, however, carrying cables wasn't always convenient or possible.
Nowadays, making something happen through wireless technology is very common, but, 20 years ago, it was something complex. Thus, the flash sychronisers were born; a device that simply detected the shooting of a flash (through the temperature and light colour variation emitted in the close environment of the photo-electric cell) and sent out a local impulse that triggered the second device. Simple and effective.
Julius' prototype takes advantage of this almost forgotten synchronism technology. Using a reflex camera and a flash placed on the back, it uses the optical system of the camera with a light projector. So, everytime a flash is detected in the area, the sychroniser triggers the local flash and projects a light message over the target to which it is pointed. Julius named this truly ingenious gadget the "Image Fulgurator".
The tourist, while taking the photograph, doesn't realize it, because the fulgurator and the flash are shot at the same time. The result, however, becomes clear after seeing the final image. "But, afterall, where did this come from?"
