Editing 360° DJI drone panorama, saved result has vertical lines

[CARPE DRONE]

OS: Windows 10

Affinity Photo 2 version (latest version, had the same issue also with previous version(s))

Steps to reproduce:

• Stich a panorama with PTGui (or take a panorama already stiched, some drones already stitch it, like in the example attached below), save as JPG or as JPEG2000
• Open the image with Affinity Photo V2, edit it:
• Layer > New Live Filter Layer > Sharpen > Clarity > set 100% clarity
• Export the result
• View the panorama with a 360 program like ptgui viewer, free trial available here: https://ptgui.com/download.html
• Alternatively, use any other 360° panorama viewer, like Ricoh: https://support.theta360.com/en/download/

Result: the panorama have all a vertical line in the middle of the sky, see a few examples I published on 360cities.

Issue: If you just adjust contract/colors (I tested) etc you won't see the vertical line/artifact, I think the Clarity adjustment is the one messing the image up, higher the clarity, more visible the vertical line, like this one (from the examples attached, viewed with ptgui viewer).

 

More examples:

See vertical line on the left of the sun

https://www.360cities.net/image/monte-rovrasc-switzerland
rotate the image and notice near the lake, same vertical line

https://www.360cities.net/image/golden-hour-at-torricella-taverne-switzerland
rotate near the mountain, see again vertical line

This doesan't appen if I do not edit the image and apply contract/color/clarify corrections with Affinity Photo 2, see unaffected panorama (not edited with Affinity) as comparison:

See examples in attachment:

• DJI_0027.JPG: original image stitched by the drone
• DJI_0027_af.jpg: image edited with Affinity Photo: edited contract, added 100% clarity
• DJI_0027_photoshop.jpg: image edited with Adobe Photoshop, edited clarity (+70% clarity), contrast, saturation

Comparing with Adobe Photoshop: Photoshop saves the image without such artifact.

I think the vertical line is produced at the edge of the imnage (left border or right border).

Hopefully you can fix this soon, so I can get rid of Photoshop and just use Affinity. Now in my drone workflows, if I use Affinity, professionally speaking, the result is unacceptable (can't sell a photo with such line in it).

@CARPE DRONE This has been previously reported, unfortunately there isn't anything that can be done. The exported image will need to be retouched to remove the visible seam.
