Lots of small glitches, but decided to share here. D7000, 35/1.8 ED, shot hand-held in the portrait orientation. This time I left the AF on, following the tutorial here:
https://luminous-landscape.com/having-fun-with-panoramas/
However, the two obvious vertical seams on the right-hand side seems to have been caused by the slight shift of the entrance pupil. This was the first time I did a pano with AF on, and this was the first time I experience this type of glitch. The exposure was, as always, fixed (this time to f5.6, 1/800, ISO100).

I'm guessing the clouds were meant to be the stars of this, rather than the "land"
Is this why you chose a 35mm lens for this?
-
Colin, thanks for dropping in and commenting.
The stars or the laned, I was intrigued by the shapes of the clouds and the way they are spread out. :)
I used 35mm (on DX) in order to keep the stitching error caused by the perspective distortion at bay, which was not very successful in this case, though.

It looks super strange with the cropped rooftops of the houses, like there is nothing underneath them, also the orange lower left makes the whole scene a bit surreal...

I am with Erik here.

Erik and Elsa, thanks for commenting.
I wanted to capture the clouds as much as possible, but would regret that there was not enough foreground left after the crop. I had to trim the top and the bottom porions of the original stitch due to the uneveness of hand-held shooting method, even though the camera was hold in a portrait orientation. Maybe I should have used a tripod or done a two-row stitch.
-
Akira why don't you try shooting two rows in portrait mode.
I love those clouds!
-
Jakov, I WILL try next time. These clouds have already gone. :'(
-
The clouds WILL come back and you WILL be ready for them :)
-
You're right, Jakov! 8)
And next time I will turn AF off.

I thought stitching errors are also caused by the images not overlapping enough ?
-
I have never done two rows of images - so forgive the blondness
I assume you just do 2 rows and the software pics up it's 2 rows??
good tip that since I am also short most of the time

Armando, when I just started to do pano, I failed to overlap the images enough, but the error caused by that never looked like this (I disabled the AF). Also, the stitches have never been straight.

Elsa, I use Photomerge in CC2015, and it does multi-row stitches. I've experimented with 2x8 and 3x3 stitches with Photomerge which analyzes the parts and detects rows and columns.

PTGui is the best stitching software out there as far as I know.
Yes, it does help when you have such good friends :)

Yes, to my understanding, it is the best pano software. Marco (Lanciani), Alan and (maybe) Frank use it to do their impressive stitches.

My Ps CS6 once did a handheld pano that was five rows tall and totaled 79 shots(as I recall). It assembled them fine, but it wasn't an interesting shot

So I think you've seen enough replies to know there's (almost) no limit.
I think there are a few well publicised Giga-pixel images on the web made from large numbers of stitched source images.
For me I have sometimes used it when I was getting wistful about not having a 50Mp camers, as a way of letting my D300 maybe capture a little more.
If you remember the old NG site, Fred/Alan used this approach quite a lot for several of his forest & landscape images.
For those of you who are more experienced in doing this, I would be interested to know the pros & cons of the different approaches.
Multi-image shots should give us the equivalent of more pixels
- Is this only of use up to (say) 10-15 source files?
- Are we only going to see the benefit when doing really large prints
or online images that people can zoom in/out of ? - Are there any drawbacks?
-
Colin, the original tiff of my initial pano has about 100MP. Sometimes I stitch only a couple of frames vertically or horizontally in order to make a wideangle image using my 35/1.8 ED on D7000, which is not necessarily for large prints but is very handy. The current Photomerge does the hand-held panos very well in many cases, alsthough it doesn't offer such a full control as on PTGui.
I have tried 2 x 12 stitch using Photomerge, but it should be capable of handling more images.
The drawback of pano using Photomerge would be:
1. The stitch error is difficult to correct.
2. You cannot really do panos for moving object or landscapes in windy conditions.

It's important to keep the enterence pupil of the lens in the same spot to avoid parllax problems. A gimball head is really usefull for this.
I prefer to shoot in portrait orientation,,, Just feels right somehow...
I see no drawbacks except for shooting non static scenes, cars or people mooving...
