Another stereo pair that i can see properly.

I have so much trouble over the years trying to resolve all the stereo shots posted in the forum.

now I seem to be getting able, to resolve certain shots, but not all?

still wondering, had eyes checked out, new glasses prescribed so it could be the reason, just a guess on the last part.

any one else have trouble with some stereos and not others?

Nicely shot -- and of course thanks for the stereo!

I can lock up pretty much anything, but some are easier than others.

Easiest are the ones that have lots of fine sharp detail, like this scene.

I usually push my own stereos to the edge of over-sharpening, just because they lock up best that way. I figure that even if I do over-sharpen the stereos by a bit, that's no big deal because they're usually presented together with a larger single image of the same subject, which is sharpened differently for that presentation.

I can't see this one. Actually, I can do very few. Often when I can see depth in a pair, the other pairs of the same maker work for me too.

Also noticed that on a tablet screen it is less difficult than on the computer monitor.

In my experience two factors determine the difficulties involved in stereo gazing:

1) The apparent angle between the center of the two pictures: this is a combination of the width of the pictures and the viewing distance. Narrow pictures and/or greater viewing distance makes it easier.

2) The distribution and number of distinct details: The eyes should be able to identify at least one distinct detail/object in each picture even when it is somewhat out of focus.

That makes viewing the 3D picture difficult if:
a: There are only details with low contrast
b: There are many different details in each picture looking the same when out of focus
c: There is a pattern of distinct details repeated with equal horizontal ditances.

Our brain must be able to pick a detail in one picture and match it with he same detail in the other picture to get the eyeball pointing correct.
That is why it helps adding a contrasty border around each picture. Then the brain can choose to get at least the frames correctly aligned. Then the rest comes easily.

Very nice, love the stereo, I always worry that the wind will change while I’m looking at a stereo pair.
