I'm using APG and I use the Neutralhazer that comes with it. I wanted to know what would happen if I would use the Neutrahazer a bit too strong. Well the result was overall better than expected. There is just one part in the panorama that totally kills it. Near the horizon:
It seems that the Neutralhazer is stronger on the sky pictures than on the rest... Why that? How can I fix this strange artifact on the last mountain before the sky beginns?
