    On of my first attempts at stereo photography:

    Hope it works! (Right click - open in new tab & backing up a little bit from the screen works best for me...)

    Good topic and with great depth.👍

    But the montage is in parallel, not for cross-viewing.😀

    Usually I cannot make these thngs work; but I CAN with this one!

    Thank you! You're right... According to this I'm able to do parallel but not cross-eyed: triaxes.com/docs/3DTheory-en/522ParallelCrosseyedviewingmetho.html Never really got the difference before.

    Yeah, I guess it depends... in this sample the images were not made with 3D in mind, so there is a high likelihood of there being too much difference in the direction I was looking, which makes the background a bit messy. But looking at some effective samples where what you described works, I think you're right... they're all at least somewhat in focus in the back.

    Glad it works! Here's another one:

    Nice content and composition, but I personally would prefer the images to have a higher resolution and the main subject to have more depth (DoF).
    It's about DoF, not 3D depth. It can be achieved by stacking several images, for example, to preserve the quality of the background.🙂

    Thanks for the tip... all of these are from shots already taken so any considerations for 3D will have to wait for shots made for it. It's good to keep in mind though.

    Interesting that you mention resolution. These shots would have 11.000 pixels in witdth... I'm downsizing them intentionally because (for me) they only work when they're displayed quite small. Is that different for you? Thanks a lot for answering all my 3D beginners questions by the way - I really appreciate it.

    Here's one in parallel

    Interesting - viewing both cross-eyed the OOF twig is behind in the one and in front in the other ...

    You can post them at any resolution, those who want to see them if they are mounted in parallel can reduce them after downloading, using software that allows this.

    Or you can post them at low resolution in parallel plus at any resolution for cross-viewing.

    Enthusiasts enjoy 3D visualization at any size after downloading to PC.

    I personally own equipment and software for 3D visualization at any size and any resolution.🙂

    You're right. I wasn't able to do cross-eyed before, but now it works and I see the same thing. Looks weird.... 😂

    I think I get the benefit of cross-eyed, because compared to the the parallel technique I'm able to view the image bigger this way and still have the effect.

    Good to know - thanks a lot!

    As stated above, I finally managed to view images cross-eyed as well. Of course I just had to try and make another example for that:

    Summar_12cm_062_cross-eyed.jpg

    For here I've limited it to 3000px but if I'm going to upload it to flickr, I'll likely go for a greater resolution, now that I know there are some people out there able to use that.

    In principle, anyone who can see objects located at relatively small distances (under 1m, under 0.5m, for example) can train to see the 3D pairs prepared for cross-viewing, free vision, without auxiliary devices.

    Auxiliary devices help to view 3D pairs with maximum comfort relative to eye strain.
    ........................
    The last pair you posted contains very clear, sharp elements, and on medium and large screens the 3D depth is impressive.👍
