I need a shot of an explorer discovering a tropical waterfall. I thought I'd get some stock footage of a waterfall and try and match it to a shot I'll create of an actor reacting with awe to the sight of the waterfall. I planned to apply a sepia filter to help match the footage. Just looking for pointers, how to best accomplish this. Again, an explorer discovering a waterfall. I don't have a waterfall, just an explorer.
