Kameraflage is possible because digital cameras see a broader spectrum of light than human eyes. By rendering content in these wavelengths we are able to create displays that are invisible to the naked eye, yet can be seen when imaged with a digital camera."
In other words, you can now place hidden messages on print ads and billboards and t-shirts and other stuff that will only be visible to people when they take a picture of it with a digital camera or a camera phone.
