Another quick tip...using the Photoshop method, you can delete material from your model (in this case a temple) that allows forground objects (in the background image) to appear to be in front of your model, helping to create the illusion of your model sitting IN the picture rather than ON it.
If you look closely at the image below, I deleted parts of the temple model to show long strands of grass that would normally be in front of the building, even though they are, in fact, in the background picture.
This is something that neither the shadow catcher, nor placing an image in the background, can do within TC.
