Fixing exposure issues in panorama
I have taken about 7 shots of the skyline and merged them together in photoshop. All is fantastic except for the distinct lines appearing on the sky separating the colours. Below is the cropped image of where the issue is the worst.

It's not too bad on the original panorama. However, since I am a big fan of high-contrast photos, the distinct lines become even worse;

Does anyone know how to get rid of those annoying lines?
Any help will be appreciated.
