I can do the cross-eyed technique but it hurts my eyes, which is the reason I vastly prefer the relaxed eyes method.

Too bad the EPOD editor doesn't see fit to post them as sets of 3 images, left two for cross-eyed viewing and right two for parallel line-of-sight viewing, then everyone can take their pick, and enjoy the 3D experience. BTW, I think when we mention cross-eyed viewing it puts people off because they think they "can't cross their eyes" as children often do. For stereo viewing we are talking about "crossing one's eyes" no more than when we read a book, which everyone with normal vision does.

The EPOD stereo pair is not for the crossed-eyes method. You can fuse the images with crossed eyes, but the relief will be reversed.

For those who can't perform the image swap that Ed kindly posted, here is a link to a pair that I reversed, for using the crossed-eyes method:

Remember that for the "free-fusing" method to work, the center of each image can't exceed your interpupilary distance. But the crossed-eye method works for any size pair, and you need not cross your eyes more than you normally would if you were looking at something about a foot in front of your face. Just back away from your monitor if you feel you are forcing it. It shouldn't cause any discomfort.

One of the image pairs is much lower resolution than the other, which detracts from the effect.

Another thing to remember is what's called the "scale model effect". For images like these to appear 3-D, the pair must be taken at a separation much, much greater than a person's interpupilary distance. It makes the object look much smaller than it would in reality, if you were really that close, while at the same time, accentuating the topographical relief.

Still, it's a neat image pair. We now have a mental image of Pluto to think of when contemplating it, instead of just that star-like speck we've seen in the eyepiece.
