Can you post CR2 RAW?
In reply to Mikael Risedal, Apr 28, 2013

It really depends how you process.

For example this is a shot in my Italy trip.  Nothing special but notice the very dark area in top left area.

You can see original CR2 raw Here

default in LR4 profile

100% cropped from above, yeah you see banding after I lifted shadow +100 in LR4

Now I applied +100 Color NR and also applied +10 Defringe in Len's correction in LR4, much better.

LR4 processed banding free, +100% shadow lifting in LR4.

And here is 100% cropped.

applied +100 Color NR and also applied +10 Defringe in Len's correction in LR4, almost banding free

Or You can try with DPP where I lifted shadow all the way in RAW tab +5 before importing into LR.  I didn't spent much time to adjust color temperature but you see DPP effectively eliminates banding.

DPP processed

Or I tried go turn DFine NR

DFine processed

Please post original CR2 file somewhere and see how I can process differently.

EDIT: just notice and I will try to process...
