Hi Dave, you already know I have problems viewing this type of image, so my comment may not help too much - both give me a central bird that seems to move backwards from left to right but never quite makes it to join as one with the right hand image. The lower pair probably make the image move closer to the rh mage.

While I was finally able to visualize them both, I couldn't really see much difference. I tried looking at them in download, but they were too big and separated for me to see them in 3D.

Thans, Dave,
I appreciate your giving it the ol’ college try!

Hi, manofg,
Most in the 3D community distribute and share their image pairs via cell phone or digital pads or tablets. The touch screens make re-sizing easier.
Thanks for giving them a try.

Like the others said, they were too wide to make the images merge in parallel view. You might try sizing them so that when you click download they actually get a little smaller. I love parallel viewing but couldn't make it happen for these.

Hi, Guy, try viewing on a tablet, iPad, or. Cellphone with touchpad controls- far easier to adjust image size. The difference between A and B is striking.

Here y’go, Guy!
just hoping that reducing image size will be of help.
Best regards,

Unless my eyes are playing tricks on me, in example "A" the bird seems to be ever so slightly more dimensional, less flat. However, separation between bird and background appears identical in both examples.

Hi, rook2c4,
I agree! Binocular depth perception is illusory, and, as with any illusion, our eyes do predictably “play tricks”.
The difference you perceive - as do most others with normal binocular depth perception (BDP) - is the result of the “through the frame” effect.
In this case the two image pairs are identical, but the “through the frame” projection of the near wingtip in pair A is the result of a difference in masking of the images, not a difference in disparities within the images. There is an imposed illusory “tilt” of the frame rather than of the image plane (the latter can be imposed by certain geometric transformations).
Thanks for looking. And commenting.

I had not answered as to which looked more three dimensional as I could not see a difference. After reading your above comment I looked again and see there is a difference in framing. Using parallel gaze again and paying attention to depth in the frame, pair B appears to me to be the deepest in the frame. Maybe I need to get my vision checked.
