Darker areas in sky at image seams

[Pierre Le.snake]

Hello,

I have made a panoramic with default options, as I am not a pixel hacker.

There are shadows in the sky that I don't know how to get rid of.

Is there a way to get rid of these shadows ?

I think that these shadows appear at image seams.

Thanks for advices.

These shadows are caused by vignetting (the photos are brighter in the
middle than the edges).
Hugin can calculate and cancel the vignetting if you optimise the
photometric parameters after alignment.
Alternatively, you can use a wider seam in enblend. Using the
'advanced' interface, Stitcher tab -> Processing -> enblend ->
options, set -l 27 for the widest possible seam.
..or you could do both.

Ok, thanks for that very clear explanation.

I'll pay more attention to that detail when taking pictures in the future.

I'll try to compensate that vignetting before merging the panoramic like you explain
