So, here you can see that I am slouching in front of a bluescreen, note: it is blue. The green band across the middle of the shot is an overlay of the image's IRE (basically the brightness of the image) note: where the image is predominantly blue, the bits that aren't me, are lit quite consistently. This will make the keying process much easier (keying is the process of cutting me out of the image, the full term is color or chroma keying)

Then, using technology known only to Druids, the blue background is removed, I am reduced to black and white (for aesthetic reasons) and placed inside a wonderful convertable.

And here you can see me doing some incredibly difficult acting.
