How to fix a poorly stitched panorama

Question

I was going through my photos from a few years ago and found a lovely panorama of some scenery (forest + sky) 3 pictures wide. I'd love to fix it up to be print-quality but really have no idea how to go about doing that. As far as I can tell, the only file I have for it is a badly stitched panorama similar to the one found here: http://thephorce.net/me/pics/grandcanyon14/gc_panorama.jpg

The problem is its actually a slight bit blurry where the photos join. I'll try to remember to link/upload the actual image when I get home.

I have the ability to use photoshop to fix it but I'm not terribly good at fiddling with things in photoshop, so any advice would be super useful it it links to a tutorial or includes the name of the technique so I can google how to actually do it :)

Answer 1

This is just my opinion, but there's no way to "fix" stitching errors other than to re-stitch the panorama, and if you don't have the original images, but just the resultant panorama, then there's no way to do that.

Answer 2

If some of the image(s) are blurry (i.e. out of focus or motion blur), there isn't any amount of post production work that is going to fix that.

If the images were shot with different settings that impacted the exposure, it is likely that you can do something about it with relative ease, although you aren't exactly guaranteed perfect results either.
