I start with hugin to make pano, than import to rawtherapee where I can apply some distortion correction (to make horizon almost a line) and then cropping and leveling in gimp.
Does anyone know better procedure? It is very likely, that I’m making some big mistake at first step
How you guys would straighten the lines? Maybe some gimp plugins?
The wavy horizon is generally caused by several things:
Control points on clouds - never put CPs on clouds.
Incorrect verticals.
Bad lens distortion correction.
Bad lens distortion correction often has other signs which I don’t see in your pano, so the first two are the culprits. You should fix this in Hugin, not afterwards.
This really is the keypoint (and no control points on clouds, as Morgan wrote). If the horizon is distorted due to the lens, put three horizontal CPs in each frame: On the left, center, and right. This usually helps a lot. And remember to check the CPs on the +2 frame (e.g. 0 and 2, 1 and 3, …). Sometimes it’s faster to set the CPs manually than running CPFind and then deleting most of them, as you don’t need many.
For straight lines, make sure you’re using Stereographic Projection - this will produce better lines straight out of a box
Then, there’s the ‘Straighten’ button in the Hugin’s ‘Move/Drag’ tab - Hugin move drag tab - PanoTools.org Wiki
using which may level the horizon, but not always
(in my experiemce, just using the Stereographic projection eliminates most of the problems so I need rarely use the Straighten)
For further finetuning the horizon, as well as foreground, background, rotation, leveling uneven series etc. I recommend using the abovementioned Move/Drag controls.
With all the above automated tools you can manipulate the entire panorama without having to add CPs manually.
Nice place, where is it?
p.s. I absolutely agree with Morgan, make sure you’re using ‘no CPs on clouds’ stitching.
Sounds like a good idea, I’ll put files on my owncloud machine and share them here, but tomorrow, cause it’s night here and I have to get my kids go to sleep now
So, if someone want to try with original files, there is a Balos file containing all jpgs.
It would be super, if you could give some suggestions based on that pictures
