My stepson works in the film industry (lighting and rigging) in Vancouver, and he sent me an e-mail highlighting this new product from a company called Rosco. The 'Windows' in this case are actual panes of glass, not the Microsoft version. I thought the effect might be of interest for people doing portrait work. The link is: http://www.rosco.com/canada/promotions/roscoview.asp
and there's a short movie there. NB: I couldn't get this page to load properly in Netscape, but after giving permission to an ActiveX control for a Windows Media Player extension in Internet Explorer, it loaded fine. You can also see the movie here: http://www.rosco.com/canada/promotions/Ros...ew%202_0001.wmv
Edit: Got a clarification from my stepson. It's actually a gel that's applied to the window with a squeegee, and works in synch with a polarizing filter on the camera.
