You can create your own red/blue 3D images to print, or look at on a computer screen, using a normal digital camera and some image processing software. For this activity we explain how to use Adobe Photoshop, but you should be able to get the same results using similar programs by playing around with the tools and settings.
To recreate this 3D effect in print or on a computer screen, we need to simulate binocular vision. In short, we need to take two photos of our subject, separated by a short distance (the distance between your eyes: about 3 inches), then make it so your left eye only sees the left image and your right eye only sees the right. To do this we will use red/blue 3D glasses and when viewed through the glasses, our photo will appear three-dimensional!
