While not as cumbersome as a cloak, the Ishu scarf, according to creator Saif Siddiqui, allows the wearer to become unrecognisable when someone takes their photo with a smart phone or uses flash photography.

"The tech behind the Ishu ensures pictures black out," Siddiqui told Fairfax Media.

"The application possibilities are endless including working with museums and art galleries where flash photography is prohibited as well as working with luxury venues on interior design such as [private members club] Soho House where pictures are not allowed.

"I came up with it when some friends tried taking a picture of me six years ago on a bike in my hometown Amsterdam. The reflector ruined the picture and I thought how cool it would be to be able to wear or hold something which can ruin a picture completely."

The monochrome pattern scarf, which retails for anywhere between $350 to $710, has been worn by Cameron Diaz, Paris Hilton and singer Nick Jonas. The blurry, blackened results have since been published via the brand's official Instagram account.

"The day celebrities start starving themselves of publicity and wearing silly reflective scarves is the day their careers start to end, not mine," Sydney paparazzo Jamie Fawcett said.

"It only works if you use flash photography. These products have been around for ages. They've been very, very slow on the uptake. Most celebrities wouldn't dream of missing their paparazzi moment. Look at Taylor Swift and Kim Kardashian. Do you expect them to be donning one?

"I think it would be great if used by people like Joel and Benji Madden, as we can't sell their pictures anyway."

Colour and visual literacy expert Zena O'Connor says the premise of the scarf, and the soon to be released iPhone case, is the same as high-vis, safety clothing.

"Incorporating the reflector particles in a scarf is a great idea because you can cover more area of the head and body, as well as babies, with the scarf," she said.
