Get a digital camera.
A tripod.
Make sure it's a good enough camera with a timer, 30 sec. burst shots will be great if it has it.
Depending on if it has a timer or burst, just set it to either.
Next, put the camera on the tripod. Set the timer/burst and go do something. Once the picture clicks, if you are using a timer.. do the same thing again but DONT move the camera. If you are using the burst, just move around and do different things within the timeframe (depending on your burst feature).
Do this about 4-5 times and use an image photoshop (assuming u have it) and layer it on top of each other. Set the opacity on each layer so you can see the one on the bottom and just start cropping and shading the parts you don't need.
