shadow effect on photos

[Xenor84]

I have to simulate the shadow of a bench that I made in 3d, inside a photo that does as background to my rendering and that depicts a road.how do I have to proceed? Thank you.

put a colored floor like floor. choose a color that is complementary to the colors of the bench, it is usually used green or blue.
then take the render, open it in photoshop and apply an alpha filter on the color of the floor.

The technique is called chromakey
