panorama problem

Imagine being in front of the midpoint of a twenty mile long wall .
Imagine the wall is level and an even hight throughout it’s length
If I stand a mile from this mid point and take several shots of the wall I can stitch these shots together to form a panorama and things look pretty normal.

If I stand 50 feet from the wall and attempt the same the shots when stitched together to the left of the midpoint disappear to a point as do those on the left .

The shots at the mid point meet at an angle because of the convergance of each side of the centerline .A shot dead on the centerline should be parallel .

Two questions does the eye automatically correct for this situation and secondly is there a way of correcting this photographic effect .

You would have to keep the film plane parallel to the wall, so the camera should be moved to the left not just rotated to the left.

This would correct the convergence problem, but the problem with making a panorama by moving parallel with the wall and clicking the camera, is the

objects like trees are repeated each time in a different location. One

becomes 4 or 5 trees depending on how many camera clicks made. That still

be the best solution in some cases.

Thanks for the help and suggestions . I have given it some thought in the last few days and for the most part I thin the functions are almost linear ,with the exception of the area immediately adjacent to the normal point
[where everything is at 90 degrees to the object being photographed] of the
object being shot . So I will try to use slices to make adjustments to this area and see how that compares to the excellent references suggested . —
