Bored?? try this out - it will waste your time quickly and you
will enjoy the effect.
Fun, Fun, Fun with Stereo

I enjoy photography and making stereo photos whenever possible with
just a single lens camera. Cars are a great subject so will do them
frequently. It is possible to view these stereos with your "naked"
eye, i.e. without any aids, and still get the stereo effect. There
are 2 methods used to view them this way - it's called "free" viewing.
FYI: You already see in Stereo if you have two good eyes - your depth perception.
These two methods change your focal points when looking at objects.
The first method is the parallel method which is typically how you find
photos set up to view with a hand held stereo viewer (stereo optican).
The normal maximum size that you will find these photos in is about 3 1/2
inches to 4 inches per photo as that is just about the maximum width that
your eyes can handle with this method. There are cheap lens on the
market that allow you to view parallel sets of photos if you don't want
to train your eyes (and brain) to do this method. Use the internet and
search for "stereo photos" or "3-D photography"
|How to view with the parallel method:
(same as for the 3-D computer art )
HOW TO: Stare at center
black division and let your eyes relax. With a little practice, you will
be able to fuse the two photos into one and see the picture in "3-D." You
will feel like your eyes are looking beyond the images at first. Your "focal
point" will be "behind" the image. When you're finally able to view the
3-D image you may notice the two original images off to the sides (don't
look at them!!). This imaging is a lot easier to bring into focus than
the 3-D computer artwork that has been so popular in the past decade. Once
you are practiced at this, you will be able to view the 3-D effect anywhere
from 8 inches to 3 feet or more away from the screen.
For Practice, try out this photo in 2 sizes - the smaller one will
be easier to do at first.
(hint - scroll so that you only see 1 set of photos)

The second method is called "Cross-eyed" viewing and it's the method
I now prefer to view stereos in but it will not work on photos set up for
parallel viewing as the photos are reversed since your focal point is changed
for this method. It will be in front of your set of pictures instead
of behind, thus reversing how your brain sees the images. This method
takes more practice than the // viewing technique but once you have mastered
it, you will understand why it is my choice for viewing photos. With
this method you can view images that are larger than 4" in width and see
much more detail in the photos.
.Click on any of the photos below to view them with the X-eyed
|HOW TO for X-eyed Viewing:
For this method, your focal point for viewing image will be in FRONT of
the image. The easiest way to establish this focal point is to hold a pencil
or finger or other pointed object (not responsible for your misuse) in
front of your eyes about 8 inches (20cm). Stare at the point with the image
in the background. As your eyes become accustomed to keeping track of the
point, you will start to notice the background stereo pictures to merge
together forming a third picture. The middle image will appear in
3-D. When you are comfortable viewing the images in this fashion, you will
notice that you can "look" at various points in the image. The advantage
of this method over parallel viewing is that you can look at larger stereos
and get more detail. Stereos set up for "crossed eye" viewing are positioned
in the reverse order from the normal, old-fashioned, parallel stereos.
You will not get the proper effect if you look at a parallel photo set
using the crossed eye method. You will find X-eyed photo sets on the internet
but rarely on paper.
