Hello, I am looking to shoot myself playing the piano at home, however, the look i want is a dark seamless room with an overhead light ( Beam preferred ) with minimal budget. How many lights and what types of lights can I use for that look , knowing that I can manage to bring a black chroma key (3x5) behind to make a dark look from behind and maybe some wooden vinyls on the ground. Room dimensions: -12 m long -3.5 m wide -2.5 m - 3 m Height
