This morning I made for my new Top Secret Community Project a small Studio Setup. It is maybe not the best but it is a good start.
You can use the Studio Setup to present your models in an neutral environment.
Here are some examples
As you can see in the examples above the Background in the image on the left is much more white then on the right. That is because the white color is cranked up with a Hue/Saturation not.
Just connect the Hue/Saturation Node to the Color Input of the Diffuse Schader of the Background Plane.
Btw the model in the image on the right is a 3D Scan of Geoffry Marchal you can download it at Blendswap.com
