Hi all,
in every turorial, in every example i have seen, when you make multi row multi line gigapanorama, i only see that the pictures / tiles are photographed in portrait format and not in landscape.
Why this?
The only reason i can imagine, is perspective distortion (oops, right word?). BUT ... if you take the pictures either in landscape or portrait, you always have such distortions. In one case more horizontal, in the other case more vertical.
So can anyone explain why every tutorial show portrait mode?
Thank you!
greetings from germany

My understanding for portrait has always been because of getting the height in a photo using portrait whilst you do not with landscape. With portrait and the height takes less shots? Only think this from when I took panoramics for printing rather than converting to VT.

Possibly originated because the simplest pano heads have the cameras mounted this way.
It can sometimes have an advantage in that it is possible to shoot a pano in a single row, where a landscape pano with the same focal length would need two.
In a single-row pano, it does probably reduce distortion in the middle of the pano, the bit you look at most.

Hi Chris!
As UKPano already mentioned: you need fewer vertical moves shooting in portrait-mode because you use the longer side of your format for getting most of the height.
On the other hand sometimes it can be preferable to have fewer shots horizontally - moving clouds as example. In that case better use landscape.
Basically it does not matter which orientation you use - but in portrait mode you don´t need an L-bracket . .

another idea preferring the portrait against landscape can be the camera & panohead combination.
In landscape modus a camera can more easily conlict with the arm of panohead. the merlin/panogear e.g. I can put the cam more easily into NPP and the up/down

Hi Klaus, hi everyone else.
I see there is no clear explanation. Hmm, maybe tradition is the real reason 
The number of shots? On multi line multi row panoramas, if you take the pictures landscape or portrait, the area you need will be covered with nearly the same number of shots. The less you have to take vertical the more you must take horizontal. a * b = b * a.
So the only advantage i see is on one line panos, where you can catch more heigth.
Thank you all!

Guess you mean one-row panos here. Yes - in that case it´s obvious.
But there are other reasons:
1) you don´t need a L-bracket if you mount the camera in portrait-mode.
2) you cover a wider vertical angle with each shot - that means
3) you don´t have less vertical movement - which can be more critical than horizontal movement.
4) horizontal moving small steps can be faster - and vertical you need to move only few steps then.
5) it´s also a matter of taste.
In my eyes the most relevant item is that you don´t need a L-bracket. This one not only means additional
costs but also a more complex alignment usually.
And in terms of manual heads: not every head allows it anyway.

Beause of the way our planet is organised, above us is often less sharp detail to see then below us.
In a multirow pano the top row of photos will be harder to stitch together in case of landscape mode then in case of portrait mode.
In portrait mode the lower part of the photo often show details that can be connected to a photo in the lower row. In landschape mode you might have a top row of monocolor photos.
Of course, when using a panorobot that stores position of each photos, there is no problem shooting horizontally.

Right - though they use a rather expensive pano-head there . . . .
Indeed it´s better to use landscape when you have moving clouds because you cover a wider horizontal angle.

On some panoheads, portrait orientation allows the arm parallell to the ground to be about 2 to 3 inches shorter, which results in less torque where the horizontal bars are attached. This matters a lot with heavier cameras/lens combinations.

Portrait specific words, portrait is a close up of person face and body for a canvas. Landscape describes artistic outdoor scenes a wide view area.

Hey Hank!
But it rises issues regarding the Nadir when shooting a sphere: The "Nadir-hole" grows the shorter the vertical arm´s length is. The longer the arm the steeper the camera´s downlook-angle and the smaller the Nadir-circle. That´s vital for getting a small Nadir-hole.
Of coures that´s only related to spherical panos.
Having a good and sturdy construction of the arm the length of the vertical arm doesn´t matter at all even with heavy loads:

Oops 
: i only right now see that you were talking of the horizontal arm . .
It´s length must allow to use cameras having a battery-grip.
