kameraflage: You See, It Sees – Different Sights
Aug 2nd, 2007 by Mike Bennett
Clever clever. kameraflage is a way of augmenting your visual environment with extra information. The extra information can be seen by digital cameras but won’t be seen by the human eye! No special software is required for your digital camera.

In the above photo you can see an example where a streak of lightening can be seen on a model’s t-shirt when the t-shirt is viewed via a mobile phone camera. The lightening is printed on her t-shirt but the “colours” (wavelengths of light) used for printing aren’t perceivable by the human eye but are picked up by digital cameras. There’s more details about the technology here.
There’s a number of usage suggestions for the techology on the kameraflage website. You could imagine extending their idea but without digital cameras. Imagine multiple people sitting around using a shared surface computer (such as a DiamondTouch). Each person is wearing glasses with slightly different colour tints, so each person would be able to view a “personal” image on the surface that the other users won’t see. Or you’re going to the cinema and depending on which glasses you wear the film has a different age rating because different parts of the film are “cleaned up” for younger age groups. Alternatively wear these glasses during the film and get in for cheaper because you’ll see inserted advertisements on-screen?
