Stereoscopic images of FLW work

Would people be interested in seeing some Stereo photos of Taliesin and s few other FLW works?

Example: ImageIMG_7851 by Owen Collins

They can be printed and put in an old fashioned stereoscope to view in 3d.

I have uploaded a few to flickr and can do more.

Most interesting. One can sometimes get the desired effect by allowing one's eyes to focus on a distant point rather than on the picture
plane; the two photos blend into one and the 3D image appears. Remember the "Magic Eye" images of a couple of decades ago ?

I wasn't able to achieve that with this photo, viewed on the screen . . .

Yes, I'd enjoy seeing more. I was able to get the effect with an iPhone (held vertically or horizontally but not, so far, with a laptop.

Huh. I guess I'm seeing the above image in 3D on the phone; I'd need a couple more examples (perhaps with more extreme contrast between far and near forms ?) to be sure . . .

Here is another one:

ImageIMG_7766 by Owen Collins, on Flickr

If you follow the images back to Flickr, each image allows you to download the full size image so you can print them out to view in a traditional stereoscope.

I have some Taliesin West, some Taliesin, some Hollyhock. Just the places I have recently (past 3 years) visited.

Nice shots

If you swap the images (Left to right, right to left) you can see it on a laptop.
It is what is sometimes called 'cross viewing' vs. 'parallel viewing'.

Here is an example: http://yowayowacamera.com/banana/20110620112230.html

It worked for me SDR. I forgot that little trick. Very effective, especially the tiger lillies in the forground.

I'm struggling to understand cross viewing vs parallel viewing. What method(s) are used in each case ? Maybe if the pairs were shown at the same size . . . ?

Cross viewing you simply cross your eyes until a third image forms in the middle, then 'relax' your eyes a little and the 3-D image should appear in the middle.

I think parallel works best with a viewer, I can't focus close enough anymore.

How does the image coalesce in parallel viewing ? Or doesn't it---that happens in the brain ?

All vision is ultimately in the brain, but yes.

I would think that the 3-D viewers for VR should work perfectly with the parallel images, wheras the Cross Viewing doesn't need glasses.

The most intense and impressive 3D viewing experience I've had, by far, was provided by a set-up I came upon at a gallery or museum
---I don't remember where. A pair of back-lighted color transparencies was visible behind a viewing mask one put one's face up to. Like any
Kodachrome slide, the color was pure and the resolution very high. The illusion of objects in space---I recall a red rose---was immediate and
stunning.

If cross-viewing amounts to just crossing your eyes, strabismus doesn't help one bit.

It isn't so much a crossing of the eyes, as a focus on a distant wall rather than on the page or screen. But I suppose strabismus wouldn't help . . .
