|This is pretty much the desktop setup I use now for most of my photography. It offers maximum flexibility in a relatively small space.
Two light stands are located on he table with eh cube and provide the overall light, a third stand may be positioned on the floor, in front of the cube to give stronger high lights.
The third light is sometimes placed above the cube and looks down, I even have another table top stand that goes into the light cube for back lighting when I need it.
I have also used my light box inside the light cube to provide back lighting on flat objects or translucent slabs.
