Revit Interior 3D View - PDF Darker than shown in Revit

[samuelzergling]

Please see attached image. This is a standard 3D view interior w/ shadow and the poche turned on. The intent is a daylighting study. In Revit, the image is nice and shows well to the client that the interior areas are bright from the proposed window arrangements. 

The PDF transition screws it up, almost as if over-exposing the distant areas. The worst part is the far right window in the back is a box bay. It should be very bright, and the PDF makes it dark. It's counterintuitive. 

I've checked materials and all glass types are the same. 

Thanks for any help. 3D interiors can be a super fast and marketable way to show interiors to clients.

Have you tried adjusting the shadow and decrease the value so it won't show up dark?

@syman2000 I appreciate the attempt. Yes I have shadows at 10 and light at 100. The question is saying the image is rendered differently from what you see in Revit to PDF. It should show the same thing.
