Hi, I wonder if you guys could give a better solution to blending these two images I shot some time ago.
The sky portion comes from Siril, and the foreground from median stacking on gimp.
Below is the end result I got. I’m still not completely satisfied regarding the blending, for one reason: the appearance of subtle horizontal bands in the horizon, where the sky meets the ground. I double checked the raws and there’s no banding there. I don’t want to get rid completely of the pollution and mist, since it was part of the scene, and I think it gives a more realistic feeling. I just want to get rid of the bands, but so far no success. I suspect the bands originate from the blending in gimp, more exactly, from the gradient tool.
