When I was a student at the University of Bradford, I took a module in Stereoscopy. At the time, I was a cornet player with the University of Bradford and wanted my project to be based on taking photos of the cornet. Using a camera from the University, I took two photos of the same image where one is slightly shifted, layered the two photos, adjusted the red, green, and blue, and then shifted one of the images onto the other. If you have a pair of red/blue glasses, you can see the 3D effect. With the different images, I experimented to get more depth and change focus. Enjoy!
