Chris, your pair looked a little funny on my phone, so I took a look on my computer monitor. I think you have left-and-right reversed.

I just remembered that you are a visual dyslexic, Joe. I wonder if that has anything to do with the way you interpret stereo pairs? On May 14, 2015 11:27 AM, "Chuck Hards" <chuck.hards@gmail.com> wrote:

Chuck, your images are "anti-stereo" to my way of seeing stereo. But then I look through them and do not cross my eyes. I would bet that is you put your photos in a stereo viewer they would look wrong to you. Chris' method definitely is not a mistake; it's just another way to present stereo images.

Joe, since Chris was talking about the crossed-eye method, and commented on my stereo pairs, I assumed he used the same orientation that I did. I have a very old WWII era stereo viewer, I used to do work for an aerial survey company when I was young, and we used stereo pairs quite often. For printed pairs, the reversed orientation from what I use is great and was the accepted normal orientation for using an optical viewer. But for pairs on a video screen, the crossed-eye method is so instant and easy that I prefer it. It's too awkward trying to hold the stereo viewer up to a screen. And it takes too long for me for the "stare through the image" method to kick-in. Thanks, C. On 5/14/15, Joe Bauman via Utah-Astronomy <utah-astronomy@mailman.xmission.com> wrote:

Oh, my, a controversy where everybody is right! How did that happen? Chris' pair are oriented correctly for Joe's method of viewing, while Chuck's posts are for cross eyed viewing. You can use Chris's pair both ways if you have Windows Snipping Tool. Snip the image on the right side of Chris' pair, display it on the left side of Chirs's pair so there are three trail images on the screen. Then you can see the left two images in cross-eyed stereo and the right two images with Joe's method. By doing this you can easily see which pair orientation is correct for the method of viewing you are using. The only flaw in Joe's method is it is limited by the amount one can widen their lines of sight beyond parallel (looking wall-eyed). Very few people can do that, so Joe's method will work for most people for images spaced no wider than their eyeball spacing for images no wider than that spacing. However, the cross-eyed method works quite well on large images and thus wider spacing as well as on small images. All of my comments apply for naked-eye viewing, that is, without optical aids. Very good image pairs Chuck. Ed Stimpson Quoting Chuck Hards <chuck.hards@gmail.com>:

If you sit back about 3 to 4 feet from your computer monitor, using the crossed-eye method will cross your eyes about the same amount as if you were looking at something normally about ten inches in front of your face.

I find crossing my eyes much easier than diverging them for 3D pairs that are large enough to require that. Bring on the resolution! I'll cross my eyes all day long for big beautiful 3D pairs. On Thu, May 14, 2015 at 2:26 PM, Chuck Hards <chuck.hards@gmail.com> wrote:
