Field of View on Pano's

This subject has gotten hopelessly tangled in a separate, but related discussion, so I thought I'd break it out into a new, "clean" thread. User allenhuffman will want to chime in on this - he's got a lot of pano images, whereas I have only a handful of examples, acquired elsewhere. in short, it's not really my "thing," so forgive me if I'm misunderstanding some aspect of it.

Here's the demo album:

(demo album removed)

It's using the same equirectangular image, but each with a different field of view (FOV). I thought that a lower FOV would be more "zoomed in," with larger values zooming out. What I'm seeing is the opposite - FOV 20 is more zoomed out than FOV 70. FOV 20 is providing a wider field of view than FOV 70.

And then, at FOV 180, the image inverts. At FOV 270, it's still inverted, and also zoomed out more. So, the zooming seems to be behaving in the opposite way than what it does at values less than 180.

I'm mystified, to say the least. ;)

The revised lightbox script files are provided in this thread:

The behavior now seems to be operating as expected. Loved the inverted images before, however! Fun for the whole family. ;)

Demo album updated, if anyone wants to look at it.

BTW, credit where credit is due, to Louis A. Davidson:

He was the primary user of my old MatrixPano skin, and a friend of a longtime coworker of mine.

His images carry his copyright, so please don't copy them without permission. :)

ETA: I prefer the "slow roll" default on his site.

I went back and grabbed my original (not modified by JAlbum) photos and recreated that section of my library using the core update, and the .js updates, and now I get much better results.

I still need to work on my older images that have no metadata and see what it does, but I think if I had encountered it in this state, I wouldn't have seen any issues (and been unaware that it could be modifying my original JPG files).

Great work to all.
