Ah! Now THAT'S much clearer.

If you haven't videoed the "person" against some well lit blue or green screen then we are talking compromise.

Get back and tell us. Why not post a still of the person so we can "see" and then gauge what could happen next.

There is STILL much than can be achieved, and can give an appealing look. It all depends on the flavour and final look you are after. I'm thinking Bezier masking with a dash of BG chroma keying if poss?

If needs be, and you haven't videoed the person against a chroma key background, would it be possible to do a re-shoot? Just the person that is?
