How to view
my 3D Photos
3D Images on this website will be found in two formats
- pairs, and triple images. To view the triple images, use your glasses on the
left two images, or "Freeview" the right two images. Images only in pairs must
be "Freeviewed"

Glasses or Viewers

First of all, there are no anylglyphs here (red and blue
style). The glasses we refer to have clear lenses, and they simply help you to
focus on the images. Hold your glasses right on your face, and start with your
image about 10 inches away. From there, just focus and enjoy! Contact
me if you need a pair!
How to "Freeview" 3D photos, with no glasses or viewers!
Each stereo view consists of two images, one
for each eye. Free viewing is the technique that will allow you to direct
each of these images separately and simultaneously into each eye. Once
that happens, you are said to have "fused" the pair of images into a stereo
view. This can be a little tricky, and some people have great difficulty
doing it at first. It may take a little practice, but once you get it,
it should pop out at you!
At the bottom of this page a 3D image is
loading with which you can practice. All of the two image pairs on this web site
are set up for "cross-eyed" freeviewing. That means the left image is for
your right eye, and the right image is for your left eye. (This page was
designed on a display of 800x600, with the images in the center.) If you
can't get the whole image to fit, try to center the two images in your
browser window.
Looking at the pair normally, you will
see something similar to this:
Now, cross your eyes, so that the pair
of images will double into four images. They will be somewhat out of focus.
If you can't cross, try looking at the tip of your nose, then without looking
at the screen, 'see' the screen, while looking at your nose. Some people
use their finger between their face and the screen.
Next, slowly uncross your eyes, and "see"
with your mind what is happening to the images. At some point, the two
pairs of images you are seeing will begin to overlap:
Indicated by the colored area is the part
where you must direct your attention - that area of overlap is where you
will fuse the left and right images of the pair. Fusion (yet still without
focus) will look like so:
At this point, your eyes are crossed just
the right amount, but your eyes are telling your brain that they are pointing
at something about four inches in front of your face - so that's where
your eyes are focused. You must dissociate the focus from the pointing,
without changing the pointing of your eyes! Simply continue to keep your
eyes crossed, keep the blurry images fused, and relax. Examine the blurry
details in the fused center image. In a few moments, your brain will direct
your eyes to focus on these details without uncrossing. The result is magical,
as the image pops into focus:
Please note that freeviewing can stress
your eyes if you are not used to it. If you feel discomfort in the eyes,
you should stop and let them rest, trying again later. As you practice
more and more, your eyes will become accustomed to this, it will get easier
and easier with no pain. (Practice makes perfect!)
If you continue to have trouble, one helpful
trick is to use your index finger as a guide for your eyes: hold it up
about halfway between your eyes and the screen, and focus your eyes on
the fingertip. This will help you to cross your eyes. Notice the nearly
merged pair of images in the background, as you move your finger closer
or farther from the screen. Once you have the images merged (your finger
will probably be 2/3 of the way to your nose), the trick is to allow the
focus in your eyes to relax, WITHOUT releasing the physical pointing of
your eyes at the fingertip. Just concentrate on the fused image pair.
It takes most people only a few minutes
of effort to see their first freeviewed 3D. But not until it has been practiced
for quite a while (days for most, weeks for some), does it start to come
naturally. Sadly, there are a few that just can't do it, and for them I
am working on getting or making some viewers that will aid you in freeviewing
from the computer screen!
Here's an actual 3D photo for you to practice on!
