360 Panorama + DeHaze (Hard line)

Recommended Posts

My main purpose for Affinity Photo is to edit and improve 360 panoramas.
Shot with my DJI Mini 2, Stitched with PTgui.
Background fill, color + contrast correction with Affinity Photo.
As a last step i do a DeHaze filter like I used to on Darktable and RAWTherapee.
Fill Zenith wit Skyfill > Fill > Mirror ball.

On both Darktable and RAWTherapee i never had this issue but with Affinity i get a hard line on both ends of the image.
Is there a workaround to have a more linair DeHaze?

Hi Dj4n90,

Welcome to the forums :)

If possible could you provide a sample file of this image prior to the hard line appearing when using the Haze Removal tool? This will allow me to do some tests at my end in order to give you the best advice.


Please tag me using @ in your reply so I can be sure to respond ASAP.

Here's a solution providing you have a sense of humour
The line is caused by the haze filter doing different things to the edge pixels on both sides, so:
Double the width of the canvas
Duplicate the image and right align the duplicate
Run the dehaze filter - I used default values
Crop image back to original 16000 x 8000 keeping the crop well away from the sides
Inspect with Live projection/Equirectangular - no line

Zip contains full sized jpeg
