After our not-so-impressive attempt at a green screen background for possums, we posted our video online in case anyone else wanted to try. We have a response! Someone named 'Jacques DuLong' has done an amazing job - we had to look carefully to check that it really was our possum. The spooky thing... after all this technology, the new background looks almost identical to our backyard, right down to the pair of lawn statues! Welcome home, possum!
