Thanks Dogz!

I think the easiest way to do this type of photo is the way I did it. Place yourself infront of a window for natural light. Place the camera on the sill and set the timer.

This way you get nice natural light that is directed through the window and focuses directly on you and allows the background to be dark. Put Chubby's face as close to yours as possible and take the pic. You can always crop out the background to centre the two faces in the pic.
