Reactivated my once found f11/26mm Hypergon lens to do some stereo imaging, as this demands sharpness everywhere...



Viewing Instructions:
1) look at the image, center on the middle gap between them (with your glasses on that you need for reading this sharp = in focus)
2) place the pointer finger at your nose tip without changing your viewing
3) now still looking straigt to the image, try to focus on your finger
4) move the finger towards the gap between the images
5) follow the finger while keeping focused on it
6) at a certain moment an image "between the images" will appear (looking three dimensional); your finger will be approx. 20cm = 8 inches away from your nose (depending on viewing distance from screen)
7) move your concentration towards that "image between the images" and leave it there (and remove your finger then...)
8 ) that's it...

Oh WOW!
I am blown away!
Followed your directions and the image popped out of the screen.
Still flabbergasted.
Amazing Klaus

Happy that this worked for you! Have been asked how to make this visible,
so I came up with this mini-tutorial. For me it is automatic, as I have done
it so often for many years now....

Here is another one...



If there is some interest in how to take those images, I would be willing to write
up a short tutorial, as it is quite easy actually and needs no equipment ...

Well done, Klaus.

I've done some stereo imaging too, so it's not difficult for me to 'see' yours. Wink

Very nice stereos, although I find viewing more satisfactory with a more distinct demarcation between the two frames.

Fascinating! But my eyes keep wanting to focus back on the image on the screen. It's hard keeping focus on a point in thin air once I move my finger away.

Try letting your focus drift a little beyond the surface of the screen.

If you just cross your eyes, and overlap the two images, it also works.
