,,,,,,,,  It's not that the effects aren't seen so much as your experience
allows you to see more of the existing detail and interpret it better than
someone new to the experience. The 3D Wizard images I now have to work with
often seem to exhibit cardboard cutout effects due partially to the close
together lenses and partially to circumstances like people standing in front
of walls. As I study the images closely I observe that stereopsis does exist
even in the *cutouts* and as I observe it, the flat effect becomes less
significant.

I seem to be noticing it more these days, not necessarily in images but in
ordinary surroundings. It's like we aren't aware of such an effect till it's
observed in stereo photos, and then by association we are able to observe it
in the surroundings. Usually true of distant objects and scenes or with
peripheral vision. As soon as I study a scene a bit more and develop a
knowledge of the subtler depth clues, the effect diminishes.

*****  Yes I completely agree. It is a matter of becoming used to stereo
images. They become more fun with greater experience. :-)
