From what I remember of this project, part of it was to capture a mirror image along with other photos. For this, I first captured the picture of any tree you would see (this was at my old high school), then I mirrored it and cut off the top parts of the tree, finally separating the colour between red and blue to represent Heaven and Hell. The image represents balance and the control of good and evil, with the orientation being flipped with the colour on top being how the viewer would see the world today.
