The Image Fulgulator is a concept device meant to help you get pictures with extra details. The device is automatically triggered when another camera flash goes off. That means you can insert those extra details in other people’s photos.

Julius von Bismark said about the Flgurator:

In principle, the Fulgurator can be used anywhere where there is another camera nearby that is being used with a flash. It operates via a kind of reactive flash projection that enables an image to be projected on an object exactly at the moment when someone else is photographing it. The intervention is unobtrusive because it takes only a few milliseconds. Every photo another photographer takes of an object at which the Fulgurator is also aimed is affected by the manipulation. Hence visual information can be smuggled unnoticed into the images of others

The device is so fast that it can’t be picked up by human eyes. The photographers will spot the extra images only when they will look at the pictures. Check out the photo above taken at Barack Obama’s speech in Germany. I believe that cross isn’t supposed to be there, is it? How much will such a device cost?
