“Freeviewing” Tips

I the last few blog posts have posted some stereo pairs for you to see what they look like and try to “freeview” them. Above is another pair for you. This is a shot of my back yard that comes through great in 3-D.

I suppose a couple of “freeviewing” tips are in order for those who want to really try to “see” the 3-D images. First of all you must get the images to the right size. When you pull up the blog page the images are too small. After you click on them they will generally be too big. You see it’s all about distance & proportions.

If you are going to “freeview” the 3-D image the stereo pairs must be about the same distance from the center of one picture to the center of the other picture as the distance between your eyes. Now this varies a little from person to person but averages between 65 and 75 millimeters, or about 2 ½” to 2 ¾”.

What you must do is set your browser window to partial (not full) screen view and play with it a little until the pictures are the right distance apart. Then you just stare at the middle and after a few moments your brain will make the adjustment and then it suddenly appears in 3-D!

You may also have to vary your distance from the screen a little and work at it at first to “train” your eyes and brain but eventually if you are one of the 50% that can “freeview” you will quickly & easily make the proper adjustments and “see” almost instantly.

Now for those of you who cannot do the “freeview” thing, stay tuned for my next blog post where I will discuss the various viewers available.
