Hmm, very nice idea to rebuild my footage scene. My intention is at final to build burning cottages at the left site on the footage - the follow are just rendertests.

Your rebuild composition is perfect - but when you look at this picture does anyone identify this as realisitic picture? Why not?

This is exactly my problem, it is not the color of the light - it is the very fine unreal structure of the trees and grass and the painted look of the rock.

Take a look at this e-on spotlight picture from a VUE 6 project - this don't work with my shoot, but it is realistic!  Don't look at the hole terrain composition - the important think are the natural trees and rocks.

Here is another rendertest i working on:

So my problem is to get natural trees and rocks....

ps: HDRI images is IMHO not the solution, all i read is to render GR - radiosity rendering Light
