hi,
you don't tell which software & render engine you r using. but if you use max & vray I suggest that:
1 take background color grey
2 take vray light only one & set its intensity around 8 to 10.
3 For Render settings, use this link: http://cg.tutsplus.com/tutorials/autodesk-3d-studio-max/studio-rendering-with-3ds-max-and-vray/
