Dropping in a model to seperate background

[bmarananpineda]

Hi Everyone,
I want to drop in a model i shot on a white backdrop onto a location.
What's the best way to do this?
I know how to use the pen tool and perfectly cut the subject out and everything, but once i put the model onto the "location" shot, how do i add a shadow to them to make the image seamless?
Here is an example of how i want it to look. I shot this image normal (with subject on location.)
But how would i achieve that same shadow if i shot the background and model (on white) seperately?

thanks for your input

Find a tutorial on the internet on how to create a shadow behind a subject. Repeat the technique in the tutorial for each shadow you want except the shadow strength/opacity for each shadow will be lower than usual because of the multiple lighting. Looks like there are at least three light sources in the shot you posted.

Here's a link to the first one I found in Google. I've seen countless others.
