A question for those who have shot panoramas of the MW...do you stitch them together manually, or do you use Photoshop or other software? I tried a pano, 12 shots worth, and let PS combine them. This is what I ended up with, I know it's not supposed to have two "tails" on the right side, not sure what what happened there.

QUOTED IMAGE

I do 95% of my panoramas in Lightroom, since the newer versions can create a pano that is still a RAW image. If Lightroom can't stitch it correctly though, I use Microsoft ICE! http://research.micros​oft.com …/um/redmond/pro​jects/ice/ (external link)

It's completely free, and seriously has never mis-stitched(?) an image for me!

Never until now, I guess. That's bizarre. What lens was this? Were you, by chance, using a wide-angle zoom and changed the focal length (even if by accident)?

Lens parallax can be a problem when attempting to get images to properly align. That's the notion that as the lens moves sideways (when you rotate the camera on the tripod) there's a perspective change between near foreground objects and distant background objects -- so it's not possible to perfectly match the frames. Some photographers build a rig so that they move the axis of rotation to the front nose of the camera lens -- instead of back at the tripod-bolt on the camera body -- to reduce or eliminate parallax errors.

But this is such a dramatic amount of shift that I don't think it's parallax. That's why I'm wondering if you changed focal lengths between shots.

It's stitching error (PS not handling it well as opposed to user error). He's already posted the same image correctly stitched by ICE

Well, it took about two minutes to download ICE, and maybe 5 minutes, if that, to create a panorama with it. I still need to work on this stuff, but ICE looks like a great way to create panos. Thanks again!

The distortion introduced by ICE seems very severe.

It does seem to be quite severe in this example. There are all sorts of different projections you can use in ICE, so it might be worth trying some of the other options!

Not sure if you're joking? What's "struth"?

But for those who don't know, Anza Borrego is full of sculptures and this is one of them. I am holding my flashlight in front of each headlight aiming at the sky!

Ehh, I'd prefer it without the "headlights", just my opinion.

Clear skies, no moon and aurora alerts on the phone. :) Happy days.
