If you find yourself straining your eye muscles, you may be trying to focus on the air between you and the pictures, where your eyes are aiming. Slowly cross your eyes until instead of two pictures, you see three. To view cross-eyed, keep the pictures at a distance where you can comfortably focus on them. I like to use a digital camera, because the pictures are higher quality, and I can still see them right away on the screen.Įven if you use a standard film camera, the pictures can be digitized on a scanner (either at home or through the services of your film processing company) and then pasted together to be viewed on the screen or printed on a color printer. If you have an instant camera, the pictures (of course) can be viewed right away.
For cross-eyed viewing, the picture that was taken from the right side goes on the left, and the picture taken from the left side goes on the right.
The next step is to place the two pictures next to one another and cross your eyes to see the 3D view. I like to use a tripod, but some people just shift their balance from one foot to the other for each shot. Just take a picture, then move the camera to the side a little bit, then take another picture. You can use any camera you have available. The viewer is nice because it takes a little practise to see the images with the first two methods, and most people find the viewer easier and more comfortable.
The pictures can be viewed in three ways: by crossing your eyes, by focussing you eyes at infinity (called the 'parallel' method because the two lines of sight are parallel), and with an inexpensive (or homemade) 3D viewer. In this section you will see just how easy it is to take pictures that show realistic three dimensional (3D) images.
