Hi, Wayne,

I think it might be fair to point out that by applying the changes, and the realignment that you did with my image pair that resulted in a pair you judged to be comfortable to merge, the reason for that was that you had removed all the specifically intended imposed disparities that have permitted others to perceive the intended 3D effect. you essentially turned my posted image pair into two identical images with no stereopsis potential.

The fact remains that the 3D conversions I prepare using solely calculated patterns of monocular depth cue accentuation are, by many able to free view traditional two-view pairs, easy and comfortable to view. Those patterns of disparity are, explicitly, based on disparate displacements of detail point through the range of horizontal to vertical.

You are absolutely correct in suggesting that there are considerable variations in capacities for binocular depth perception. Development of that capacity begins in infancy with yoked conjugate and disconjugate vergence and accommodation and continues, in most people, to undergo subconscious training that is not complete until late adolescence to early adulthood when the ability to bifoveally see not only horizontally displaced disparities, but also those displaced vetically and all angles in between. It is now recognized that acquisition of such independent eye movements disproves the assumption that the infantile yoking of vergence is not  a low-level reflex.

Those restricted to merging images with only horizontal disparity displacements of the sort that have characterized traditional ortho stereographic image pairs for almost two centuries often encounter eyestrain when challenged by more diverse displacements.

In the paraphrased words of ol’ Carl Gauss (he of “bell-shaped curve” fame), “your mileage may vary”.
