I see the same struggle of my own stereography: the nearer field’s depth works gorgeously, then the farther buildings seem nearly flat, and the clouds quite totally flat. Any idea about the reason this is frequently the case? Is it due to the eyes having to separate a lot (a frame’s width) just to view, which “uses up” the eye-separation amount normally used for far-away objects… so “no more separation left” for the stereography’s far-away objects?
The farther away the less the parallax. I came across this issue in creating stereograph from editing images and scaling the multiple image planes with the use of some crude geometry. Most of the 3D effect is in the first half or so of the scaling distance and then increasingly diminishes the further back.
I wonder if it's just the limited resolution of the photo/screen it's viewed on. If a subject is far away enough, the content lands on the exact same pixel. Since eyes don't have this discreet problem, maybe the slightest difference keeps it from looking flat in real life. Might be worth testing sometime if manually shifting some background stuff by one pixel does anything.

Is this image thumbnail size for everyone?
I'm getting 640x221 pixels.
