Using four white panels, I built a light cage around the model. I put a strobe on the ground behind her, then I sealed the upper part of the frontal "door" with an Elinchrome Deep Indirect Rotalux 150 (in the diagram I used a beauty dish, because there isn't the right item among the diagram tools). The lower part was sealed with a silver reflector.
The result has been a really soft, white and enfolding light.
