Sky Color shift
I have this set of Raw images that I am stitching into a pano. I shot these images at 9:30 AM, moving from north-northwest to northeast toward the rising sun. As you can see, there is a pronounced non-uniformity in the sky between images 1 and 6. I was able to remove the color shift after stitching, but I would like to be able to achieve a uniform sky before stitching.

On the other hand, Affinity doesn't give you a stitched file in a raw (DNG) format. Nevertheless, it does a good job.

Was there a uniform white balance when they were shot?

yes, the problem was that the sky toward the sun is lighter than the sky away from the sun

Incidentally, this set of six images is really part of an 18 image set consisting of 3 rows / 6 panels. C1 v22 did an outstanding job stitching them into a high resolution image

It's not clear to me whether the best thing is to try to achieve a uniform sky before stitching or after. If you changed something between say Image 4 and Image 5 in your sequence, then there would be a glitch at the overlap between the two when they were stitched, perhaps. Maybe it's best to apply a linear gradient to the stitched result from right to left and change it open a graduated basis on that. After all, it does stitch it together as a raw (DNG) file, so there is still quite a lot of latitude. (As long as the last in the sequence isn't so over-exposed that highlight recovery isn't possible.

Thank you. It was easy to make the sky uniform after stitching in C1. But when I tried to stitch in Hugin, I had to go back to C1 to make the sky uniform. When stitching in Affinity Photo, sky uniformity was much better

Thank you, I was able to improve the sky using the uniformity tool the way you described. I was just hoping there was way to do it before stitching.
Affinity Photo made a decent sky directly during stitching and C1 made a very good sky after stitching via the uniformity tool.
