Hi Bruce
Not an expert, just using Hugin from time to time.
1) Give Hugin some hint about the focal length used for the images. I
did start with 30mm, and a focal length multiplier of 1.5. Hugin will
optimize this focal length for each image later.
2) Put "anchor for position" to one of the middle images from your panorama.
3) After automatic control point creation ("Feature Matching"), manually
add some vertical and/or horizontal control points before beginning
optimizations. This helps a lot with stitching of "sunsets at sea" and
architecture images.
This is easy with your pics, just follow the horizon with one horizontal
alignment pair for some of the images.
4) During the *Optimize alignment" step, do each alignment step
separately, beginning from top to bottom. After each alignment step,
check the control points with the greatest deviations. If they are
obviously wrong, delete them, and re-align. Leave them if they are
correctly set, even when they have big alignment errors.
5) Do not over-align: Stop at "Positions and Translations". Check the
preview from there.
Panorama for this 2009 sunset shot is stitching just fine after doing
this steps. There is some waves which do not fit, and need manual
intervention. This can be done with masking in Hugin before the
stitching, or healing the finished panorama in darktable or Gimp.
Hugin 2018.0.0 displays some exif information from your images: The
focus was 28-30mm, and a focal length factor of 1.5. You used a Dynax 7D
with a 18-70mm zoom. I do not understand why others in this tread are
not seeing this information.
Expert mode in Hugin requires an investment in learning, but at the end
is much less frustrating than the sometimes non-perfect results from
semi-automatic modes.
Sending you the Hugin project file in PM.
