    Hi All,

    In the last couple of days some posts have appeared in social media feeds which look 3D to varying degrees - and no, I don't have any 3D capable devices. In particular, I saw images in posts from an organisation called BitDefender which looked amazing with extraordinary depth. If you want to see what I'm seeing, Google "bitdefender notflix chubb" and hit 'Images.'

    A quick Google suggests it's to do with colour wavelengths and might also work with red on blue. Has anyone else encountered this before? Or even seeing the same? - Checking I'm not going loopy in self isolation.

    I have myself noticed that bright red on black sometimes gives a depth effect, so you're not alone.
    I don't understand the effect.

    Edit: I've researched it. It's called chromostereopsis. This is an interesting description of it: http://www.ritsumei.ac.jp/~akitaoka/scolor-e.html

    Thanks for making me feel not quite so mad, Belodion. Your link is helpful because some of the things shown there work for me and others don't, and it's clearly not a universal thing for everyone anyway.

    Many years ago I trained my vision so I could see hidden 3D Magic Eye illustrations instantly and wondered if that was leading me to see things which don't appear the same to others.

    Yes, I learnt to do the 3D viewing as well. In fact, in my photographic days, I used to do stereoscopic photography, using stereo cameras, stereo beamsplitters, even homemade stereo cameras, as well as sequential side-by-side stereo pairs with ordinary cameras. I've also done a small amount of 3D photography using phones. As you can see, I'm far more advanced in madness than you.

    That is epic. I knew coming to Android Central with this would be the right place. Android expert and 3D image specialist on the side. My only advice to anyone on the subject is don't do loads of Magic Eyes in one go 'cause it totally sends your vision bananas for a while, and then you involuntarily start looking for them in places where they just aren't.

    Penicillin cleared that up for me.
