so i just got these images printed in an album, and for the first time ever i have extreme banding in my skies. I can't see it on my calibrated screen, and i always print 4x6 tests before, can't see it there either, but when my lab open them on their screen they can see it, and it so bad that i can't leave it, its levels of banding almost like a rainbow all around them but i have no idea how to remove it, i tried adding noise etc, but since i can't see it i don't know if i am getting rid of it. i have never had this happen to any of my images, and can not think what was done differently to these images
