of course. this was all very improvised and basically done on the fly, so don't take it too serious, but this is what we did:
we shot on 7d and took empty plates to do all the removals (pictures were taken still, the camera shake was added afterward by tracking a shot done for this purpose).
then we shot leilis head in front of a greenscreen and made her turn to be able to give the balloon some z-movement. unfortunately, i messed this effect up because our trackable balloons flew away, so the "balloon" movement in the last shot is tracked and rotated manually frame by frame...
