You are speaking about horizontal disparity. But, on some stereos, youIf they have local deformations they are not very well aligned.
When zooming on these details, you may need to completely re-align theOK, but it only makes sense if the original SBS are poorly aligned
For example, in the Spider-Man case, you may have a well-align wholeSpider-Man is a composition of two stereo pairs: the background and the
Spider-Man proper. If each pair were perfectly aligned in the origin, then
the composition of the man overlaying the background would be perfectly
aligned as well.
The composition would surely require adjusting the depth of the Spider-Man
respect the background, because it would be bad if it appeared behind the
background, and it would also be bad if it appeared too much in front. This
is where I believe your "X" control in "Alignement" makes sense. They also
make sense the "X", "Y" and "D" of "Placement" because they do not spoil the
alignment, they only control the position and the zoom of the complete overlay.
But frankly, I would not use the "Y", "L", "H" and "R" of "Alignement"
because they spoil the vertical alignment, and it is very difficult to assess
the error visually.
Your explanations may be a bit confusing because there are two X tuning:OK, I understand the first for adjusting the depth of an image respect the
window, and the second for displacing both stereo sides at the same time
(I guess for placing overlays)
