Attached Link: My Gallery Image - Spanish Tourist Attraction

Heheh. I have done this before. Examine my linked image (warning - tasteful nudity).

In the notes there I said this:

*This was suprisingly difficult. Had to make a custom shadow catcher that gave a blue tint to the shadow to match the real shadows. The lighting was pretty easy though. I hacked together an IBL probe myself to get the general lighting and then one infinite light at 120% took care of the rest.

*I'm at home and my Poser file for that is at work. If I recall correctly, I did not use the "shadow catch only" option. Instead, I attached something similar to the above shadow detector (1 - Diffuse) into the Transparency input of the ground.  This makes the ground become more opaque where there is shadow, and transparent where there is light. Then I placed a dark blue color in the Ambient and turned Ambient_Value = 1, with zero Diffuse_Value and Specular_Value. By adjusting the amount of transparency and the exact color, I was able to match the shadow exactly. 

Basically this is blending a specific color with the background picture where there is shadow and no completely transparent where there is light.

When I get to work tomorrow I'll open that file and post the exact material I used.
