How to manage a perfect setup for CG Artwork (fun !!!)

So a lot of people ask us, how we made the setup for the Scene "A day at the lake" ?
Psss its not a secret, need a lot of studio people, perfect light setup from above and a huge fan for the wind. :)

OK lets start :
- Complete scene setup was buildt in Blender 3D (cycles)
- 3 sun lamps, 48 Spot lamps, 3 Area lamps
- People are from renderpeople
- Grass Setup is from our Nature Essentials
