I'm just learning some tricks. This is very very badly done, but it is my first attempt.

I tried wearing a green tshirt and doing green-screen (using keylight in after effects) at first. Which almost worked oddly enough.

Then to clean it up I crudely did a timeframed mask - which is why you might spot disappearing bits of head from time to time.

I'm starting to figure out the importance of consistent lighting ;-)
