I made a 360º from DNG files using a DJI Air 3 and I have a problem with the sky.

Anyone got any ideas how to resolve this issue?

With the Air 3 it creates a JEPG version which is slightly smaller in size bit the stitching is perfect!

What version of PTGui are you using and are you stitching raw images?  There have been severe vignetting problems reported in the past for which the cure was to convert the camera's raw images to tiff or jpeg using Photoshop/lightroom for input to PTGui.  The latest versions of PTGui have improved processing for raw images using the embedded lens correction profile so may avoid this problem.

I got PTGui Pro version 12.27. I export them as TIFF’s and see how I get on.

Hi Chritopher,

The DJI images have strong vignetting. The DNG files contain an embedded
vignetting correction profile. PTGui 13 is able to use this but PTGui
was not. So you'll get better results by first converting the DNG files
to TIFF and stitch those in PTGui.

Kind regards,
