I watched carefully what the tv-professionals did and learned specifically about improving light. So this is the result. I think the slightly yellow will be fine. In fact it is a large aluminum foil in silver and the other one in gold over a big board. It reflects the sunlight much stronger than the styrofoam board that I have used so far. There is a danger to exaggerate. So I have to try more.
