This is the best I can offer. It's not perfect, but an improvement to a degree, at least. First, a fabric-coloured Solid Color layer on Lighten mode, and paint gently (10% brush) over the darkest areas. Then the Hue/Sat layer over the top.

Yeah, no, Channel Mixer won't work here, because the tones aren't different enough.

You've restarted your computer, I trust?

Was the banding evident before you calibrated, do you remember?

Ok, I don't think that's cause for concern. As long as it's not there at 100%, you'll be fine.

What about at 50% and 25%? Banding or no banding?

Yay!

Um ... are you going to show me the photo?

Oh, ouch. It might have to be this.

262GB is slightly less than the 1/3rd free space that Brian recommends, however it should be ok. Don't let it get any fuller, though. Ok, let's try this.

Oh, gosh, no, you must NEVER do that. Leave your Color Settings exactly as they are, on "North America General Purpose 2". That is the safe setting. http://www.damiensymonds.net/2010/02/please-ignore-your-monitor-profile.html Do you still have some of those older prints? To check that they still match your screen? As long as you can prove that, then yes, this sounds like a recent lab cock-up.

Just a little bright patch on the right-hand side.

Alas, no, sorry. Sometimes depth-of-field blur can be passably sharpened for small prints; but this is motion blur, and it can't be fixed. Ditch the photo. http://www.damiensymonds.net/%3Fp%3D2573

Can you do this for us?

Use Native. 7104 should be good enough.

Great.

Maybe, or maybe not. What file format are they saved in?

Yes.

Yep, the Ultrasharps are excellent.

Download the PSD file It's going to seem like a heck of a weird process - first you make it black-and-white, then you make it skin-coloured, then finally you make it purple. But it's the only way I could find to prevent those casts, and problems with the edges.

Oh, no, then that's fabulous.

I would use a combination of patch and clone tools to get rid of them completely, then lower the layer opacity slightly. Akin to this: http://www.damiensymonds.net/patch-tool-for-eye-bags.html Do you also need advice about the moire?

Well, at the bottom, the brush opacity would need to be 100%. To fully remove the visible edge of the shadow, you know?

That looks great to me. Really well done. So the flaw is just in your masking, I'd say.
