[SOLVED] What type of rendering/lighting is it and how to reach it in unity

Hi, I am making low poly game and for better results I would like to add fancy effect like in this picture, but I am not sure what type of lighting or rendering it is. I think it might be HDR or so? How could I reach it in unity?
Thank You.

So i have been looking on google and all of these effects visible on the image are actually easily reached just by playing around with Unity Assets called Image Effects, which is free after Unity 5.0 release.
