This Invisibility Cloak Can Hide You From Photographs
The new material is specifically designed to ruin flash photography
This line of clothing accessories has a bold claim: “Privacy is back. Using fabric patterned with a special material, ISHU scarves protect the wearer from unwanted photography by harshly reflecting flashes back to the lens, Quartz reports. When the ISHU is worn around the neck, it can prevent paparazzi from taking clear photos of a person's face.
The photos would just turn out as floating glowing scarves while everything else would turn black. This is because under a strong flash, the ISHU scarves turn into a giant reflector, pushing the camera to reduced sensitivity or risk overexposing the scarves.
