That dear old cinefossil Yves from @crewstv was kind enough to Tweet this little RoscoView day for night shooting setup as used on Parenthood.
The same “Parenthood” set, same interior lighting. But because the windows are equipped with RoscoView panels, a rotation of the camera filter creates night, day or anything in between outside the windows.
RoscoView is a unique two-part window control system for film and television professionals. It consists of wide width polarizing filter installed on windows and a matching camera polarizing filter. The window filter is available in easy-to-handle acrylic panels or in the traditional soft roll form. The camera filter is optical glass. Rotating the camera filter changes the degree of cross polarization on the window where the RoscoView filter is installed. This results in 100% control of exterior brightness as seen through the window. To the naked eye, the ambient light coming into the room or studio is reduced by only one stop.
See RoscoView for more information.
