Anti-paparazzi fashion accessory to thwart flash photography. Curently in development. Next prototype expected to be ready by fall 2014.
The anti-paparazzi clutch uses an array of high-power LEDs to produce a stream of light at over 12,000 lumens.
This project began as a prototype at NYU ITP in 2008. The project has been developed into a fully functional prototype that is capable of detecting flashes and returning a burst of light fast enough and bright enough to overexpose the sensor of a camera. The approximate light output is > 12,000 lumens and the approximate effective range is up to 12'.
