a photographic studio set of matte black seamless backdrop paper sweeping in a smooth curve from the background onto the floor, the black filling the whole background and both edges of the frame and fading to pure black toward the top and sides, the matte black floor faintly visible in front, nothing else in frame, and a clear patch of matte black floor in the centre about 4 metres from the camera
