These two photos matched up pretty good I thought. Or did I try to include too much of the pic? Maybe a tighter crop?

The images are a bit small on my screen to give a dramatic stereo. Maybe a wider separation between the shots would help with that as well (I mean with the camera, not with the editor :-)).
 
This stereo deal is all new to me, so any and all advice about the best way to crop/align images is appreciated. I'm wondering if you mean cropping/aligning to make it easier for the viewer, or just the standard type of cropping, to improve the composition of the image?

It snaps in fine. I would have cropped the images so they align better within the frame, but it's not a problem.

Great sense of depth. My eye has a lot interesting paths to follow into the scene.

Ah, the Wrght Flyer. I haven't been to Kitty Hawk in years, but I feel like I'm standing there, looking at this shot (unless this is a replica in some other location ;) ) . Nice!

Very good one. Looks like some strange animal head sticking out from the stump! Great depth! I like it!

Life is like a coin.....you can spend it any way you like, but you can only spend it once!
 
Thanks! Nope, not a replica in some other place. This was the one at Kitty Hawk a while back.

So this challenge is all for YOU! :-)

Easier for the viewer, yes. When I view your stereo I see about 8mm of ghosty overlap on both the left and right edges.

I guess you just mounted the two uncropped originals side by side, right? It works fine for the stereo, there's no problem with that, but the overlap is distracting.

When I'm editing one, I'll set up the two component images as layers in a Photoshop file, with the top one at 50% opacity. Then I'll move the top layer (and rotate if necessary), so that it is aligned with the image underneath. Obviously they won't line up perfectly all over, so I choose a prominent focal point (e.g. the fork of the fallen tree), and make that coincide on both layers. Then I crop within the area covered by both layers, double the canvas width, and set them side by side (and set the top layer back to 100% of course).

I avoid Oilman's problem by always shooting the left image before the right image, and then I know that the image with the lowest file number goes on the right in the editor.

Changed the framing a bit for this image. Another one from yesterday's hike.

Nice (I love those leaves). You have a good eye for what will make a good 3D.

See my other reply about framing. If the process I described doesn't makes sense let me know, and I'll demonstrate with one of these.

Thank you. When I went on my hike I had this challenge in mind, along with some other things. I am amazed at how well this simple stereo technique works. Thank you for pushing me to try something new. I think I'm getting hooked on stereo photography. Hope I don't go permanently cross-eyed on this. ;)

Actually, it is very similar to what I figured out on my own, although I don't do the adjusted opacity overlay. I just drag one image (partially) over the other and pick a few points to line up near the edges, then slide them back. Not as precise, but seems to work. Is there some guideline for how much white space to use around and between images? I have one more ready to go and want to avoid that "ghostly overlap" issue you noticed in my first image. :)

Should I have put a health warning in the OP?

I find if I do a good job of cropping with the layers aligned I don't need a border, and I prefer them without, but borders might help those who are learning to see in stereo.
 
I've been trying and trying to see this whole 3d thing and all I've been able to achieve is sore eyes and a sore head!! Maybe my laptop screen isn't big enough to get the full effect.

I didn't have any trouble with those 3D images that were so popular in the 80's (remember those??? You'd always see a bunch of people standing outside a shop window just staring :P) so I thought I should be able to see these but no luck.

Oh well, great idea for a challenge anyway!

Cheers Olivia

I've noticed that it is a bit more difficult to get the effect on my wife's laptop PC than on my larger sharper desktop monitor. I haven't tried printing these yet, but that might also help if you feel the screen is the problem. Would love to see some of your shots in stereo. Please keep trying.

This may not look like much in 2d, but if you can get the stereo view, it's a whole different thing. :)

Sure is. :-)

I don't find it easy to lock in. I guess there was quite a lot of distance between the two shots?
