Abstract: There is described a method and an apparatus for rendering a realistic lighting on a subject to undergo chroma-key compositing into a scene environment. The method comprises providing translucent screens forming a closed environment around the subject and undergoing projection from outside to provide the realistic lighting, and identifying an area of the screens that is behind the subject and forming the contour thereof from a perspective of the camera. A withdrawable background is projected for the areas of the screens corresponding to behind the subject and to the contour of the subject, projecting, such that when an image of the subject is taken using the camera, the withdrawable background forming the contour of the subject is used to isolate the subject in the image of the subject to perform chroma-key composition.
