I apreciate this detail and the link. How does putting a gray node into the IBL work? How does it differ from using a gray infinate light with a low shadow setting? In that it is some kind of reverse point light? It blows light in from "everywhere"? I wonder if this would help me a good deal... I need to try it... I do kinda conventional studio lighting of spot, soft side fill low and harder cool side fill high on the other side. With rooms I am a mess... trying to shine a dark gray without shadow through each wall the ceiling and the floor to get what we called a "bounce flash with difuser" which was my favorite Real World lighting if I wasn't shooting super fast film on available light. I wonder if this gray IBL would soften things with my regular set up.
