Hi, Ninni!

I shoot a lot of sea horizons from shore. The best way I've found around the non-linear or wavy horizon issue is to go the Control Points tab and manually add horizontal lines to the horizon in each frame before generating any automatic control points.

Then I run Hugin cpfind to generate automatic control points.

This gives me consistent good results for a straight, level horizon.

I think it also helps Hugin find good control points since it gets to start with a set of known good horizontal control points.

Maybe that will help.

Happy panorama making!

Thank you again.
yes i know what are control points, i also added them manually but still doesnt work good. as you wrote, my subjects are seaside, landscape and not rail. I always get a non-linear horizon or the repetition of the tip of Sicily at the bottom, as you can see in the file I sent. It's a shame that such expensive cameras don't have a built-in function like in smartphones that helps you create these kinds of pics. my last try will be Ptgui latest version, if it solves automatically this problem i ll buy. do you know some A.I. service that can help in creating 360* pic?

    A few handheld shooting tricks:

    First of all concentrate on what your main subject will be. In your
    panorama, I guess the real subject is the sea and the mountain, maybe
    the wall and the pillar, but not the railing. This is very important
    because when shooting handheld, you will probably get parallax
    issues,
    unless the whole image is at the same distance from you. So to create
    the panorama, you will tell Hugin to choose points on this subject
    and
    to neglect points closer or farther than your main subject.

    I don't know if you started to read the Hugin documentation, but in
    order to understand the following suggestions, you must understand
    that
    Hugin uses "control points", points which are set on the same
    elements
    on contiguous images. Hugin usually sets control points in the
    middle of
    patches of the same colour.

    Try to take your pictures so that contiguous images will have static
    elements from this real subject in common. "Static" means
    obviously not
    on a wave or a moving car or the leaves of a tree in the wind, but
    also
    not on a cloud (unless you are trying to make a panorama of the sky
    itself). Those elements should not be too large. Not a close beach or
    big wall, but a foot print or a stone in the wall

    The more widespread are the control points, the better. For example,
    pick a few details on the coast, ideally at least two at the top
    and two
    at the bottom. For good results, the points should not be aligned, so
    that 3 points on the same the left edge of a building won't help
    as much
    as 2 on the left edge and 1 on the right edge (2 on the left edge
    and 2
    on the right edge will be even better). This means that you should
    ensure that the common part of contiguous images will allow for such
    points as much as possible. Obviously, this would not be possible for
    the part of your panorama where there is only the railing and the
    sea:
    the railing is not the main subject so that placing points on it will
    probably not give good results and I can see nothing which could
    be used
    as a control point in the sea. Which leads to my next suggestion:

    If there is a large space without any distinct element, try to
    take it
    in one picture. I am not sure if this would have been possible in
    your
    situation, but I would have tried to take the whole sea in one
    picture.
    This is also true with a not so large but important item, for
    example a
    building: try to take it whole in one picture. BTW, judging by your
    shadow, you are using your camera in portrait mode. You could also
    use
    it in landscape mode, in order to get a wider horizontal field of
    view.
    Hugin is perfectly able to create a panorama from a set containing
    portrait and landscape pictures.

    Check if there is a better place to take your pictures from.
    Sometimes,
    moving just a few steps can help make parallax issues less
    obvious. For
    example, I would have tried to take the pictures from closer to the
    railings, in order to get them out of the way as much as possible.

    One advice, less related to shooting: If you know how to use an image
    processing software like the Gimp, make Hugin create a "Normal
    panorama
    with layered TIFF output", you will get a TIFF with one layer per
    photo
    and you will be able to define precisely which photo to use for each
    zone of the panorama, which can be useful to avoid some issues
    like the
    discontinuities in the railings. This also allows you to use
    parallax to
    hide elements: if there is an ugly road sign, take one picture,
    move one
    step to the right or to the left and take the same picture, then
    in the
    panorama you can choose the visible part of each source image so that
    the road sign will "disappear". Or take a few pictures of the same
    scene
    with people moving around and you can "erase" the people.
