So not talking much, i am going to show you how to use Retouching abiities in Photoshop.
Ambient Occlusion is a method for simulating global illumination, while keeping a respectable ratio between results and computing times.It is a global method, meaning the illumination at each point is a function of other geometry in the scene.
Ambient occlusion is most often calculated by casting rays in every direction from the surface. Rays which reach the background or “sky” increase the brightness of the surface, whereas a ray which hits any other object contributes no illumination. As a result, points surrounded by a large amount of geometry are rendered dark, whereas points with little geometry on the visible hemisphere appear light.
Ambient Occulusions are cool cause they add depth and 3d look to the rendered image. We render ambient occulusion pass to give 3d look to objects . Many people just render their models by applying ambient/reflective occulusion as a shader. But this way they loose the previous material. But i am going to show you a quick and easy way to render ambient occulusion pass.
