Quick question

[Rav]

Hi guys,
I got one quick question about render that I'm working on currently. I got house which is lighted by sun + studio brightness. How can I make this wall in shadow brighter without adding another light? Any other suggestions or advices how to improve or make it more realistic requested. 
Thank you in advance,
rav.

Thank you for responding
I've tried it and the result was just like on this first photo i uploaded :/ Despite sun 2.0 walls in shadow were dark.

You need to also raise the cloudiness to .5 and raise the ambient to high... if you could send me the model I can manually set the sun the settings. I also have a few good wood plans.... see attached...

Thank you very much, you are very helpful. I've changed wood texture, looks way better. Here is my model.
Thank you once again, I appreciate it.

Sometimes with lighting you have to play with the settings.. what might work in one case will not work as well in another... depends on the geometry of the Architecture, the glossiness, reflectivity and transparency of the materials
