Methods of Viewing Stereoscopic Images
In the cross-eye view method, you look at the left image with your right eye, and look at the right image with your left eye. Place your finger between your face and the images on the screen. If you stare at this finger, your eyes become cross-eyed. While remaining cross-eyed, slowly transfer your vision from your finger tip to the center of the screen, and lower your finger. Keep staring in this way; at one point, an image will appear in stereo. This may be easier said than done, but be patient and keep practicing. When you get the knack of it, you will be able to get a stereoscopic image in 2 or 3 seconds. This method is definitely more suitable for viewing larger pictures.
In this variation of the cross-eye view method, you use a small viewing
device. In the center of a fairly thick, post-card sized card, cut out
a 3 cm (1 1/4-inch) square hole. Place the card between your face and
the images so that you can look at the left image with your right eye
and view the right image with your left eye through this hole.
Try one eye at a time, with the other eye closed, while adjusting the
position of the card.
When you have placed the card at an optimum position, open both eyes
and look at the two images through the hole. Keep looking, and soon
you will see one stereoscopic image.
Try both variations and select one that suits you better.
In this method, you look at the right image with your right eye, and
the left image with your left eye. Place your eyes about 30-40 cm
(12-20 inches) away from the monitor screen, and gaze blankly through
the screen as though you were looking at an image which is far away,
while keeping your right eye on the right image and the left eye on the
left image. Eventually the two images appear as though there were three.
Focus your attention on the center image, which should soon appear in stereo.
Some people can get the result in a minute or two; others may take longer.
Do not strain yourself; just relax and practice.
If you have a printer, you might try this method. Print the images which I have prepared for the parallel method. Hold your face close to the printed images so that your right eye is over the right image and your left eye is over the left image. Slowly pull the paper away from your face to the point where your eyes are focused on the images. It is important that each eye keeps staring at one image in front of it. You should be able to do this without too much effort. It is also a good exercise for stereoscopic viewing. Do not apply this method directly to the images that are displayed on the monitor screen. You may hurt your eyes, for which I cannot be held responsible.
The one that puts up cardboard at the center, and sees in the method where it describes in a parallel method (the 1) though this printed the screen of a parallel method or the screen of a parallel method.
Whichever method you try, practice at your own risk without straining yourself, and choose the method that suits you best. Good luck.
This is seen with special glasses. It looks in left eyes and it looks three-dimensional like red and right eyes, etc. when becoming blue and seeing. It is possible to make it by oneself though it is possible to buy from the Internet as introduced from my HP. Cardboard is prepared, center parts of eyes are made to become to about 65mm, it punctures, red cellophane is pasted to one, and blue cellophane is pasted to the other.
Please refer making though a left photograph is glasses for the anaglyph appreciation of ready-made goods.
