Here is the adjusted showroom version of the Retrolux Preview Preset I have done to generate previews. It uses the basic Kunos studio/preview setting. Its great to make clean and minimal wallpaper shots. Just add some grain in post and it looks almost like a photograph.
Move the camera around and focus on the desired location with CTRL + Left Mouse on the 3D model.





Ahh I just love the Custom showroom/preview editor 
Here is the Installation Link. Enjoy
