In this tutorial I'll show you how to import your photographs via XML, and get an average colour and brightness for each photograph. Then, using this information, we will work out the average colour and brightness of the pixels from the webcam, and place the correct colour image in its place. To achieve a movie with more depth, you just need to use more photos; the wider the range of colours and brightness, the better. You'll find the screen grabs for each step of this tutorial in the support files.
