I can also make red/cyan anaglyph images, but they require glasses to see the depth....and anaglyph embeds the parallax in the image....which doesn't work so well if objects in the image are at a variety of depths.
But 'stereo crossed' is about as good as it gets. Your own eyes adjust the parallax as you view the image and the colour is unaltered and focus is perfect.
What I'm trying to work out is how many of you can see stereo crossed images? Not everyone is able to gently cross their eyes until the left and right sides of the image merge....and depth becomes apparent. I have no difficulty at all doing this....but have no idea what proportion of people can't.
Help me out.
Can you see depth in this stereo crossed image by crossing your eyes? Let me know. Thanks. :-)
