Greenscreen background fabric for keying. The fabric is strong and thick enough. I have it custom built on an even, stretched wooden frame (Br.2,80 x H.2,20m, rest cut off) with brackets. This results in the camera ein16: 9 aspect ratio picture. With 20cm of headroom above I went up to the lower leg in the picture, about 1.20 m. I stood right in front of the green screen and positioned so that my shadow did not fall on both sides, a 1000-watt lamp to the screen. The keying worked so flawlessly.
