Title: Difference between Spherical and Cylindrical in LR 9.0 Pano Merge
Post by: robcrandall2 on December 10, 2019, 10:01:53 am

As I toggle between the two, there is a slight change. What exactly is the difference?
BTW, "Fill Edges" is a welcome addition.
(LRClassic 9.0 on Mac)
Thanks.

The spherical projection fits the pano onto the inside of a virtual sphere, the cylindrical onto a virtual cylinder.  (The perspective projection fits it onto a flat space.)  Adobe provides some guidance (https://helpx.adobe.com/lightroom-classic/help/panorama.html) on when to use each, but when you're unsure, just try each and decide for yourself which best suits your image.

Because of that : in cylindrical the vertical lines remain straight, only the horizontals curve (campbellsoup tin) : In spherical both curve ( globe)

The small/ big difference depends on the vertical anglesize of you panorama;

thanks, that's a good way of explaining it.
