Re: Bad Gradation at shadow area

Which method did you use to make the colour mod? (e.g. HSL, curves...).

I would suggest that unless the photographer can supply you with a 16 bit file (i.e. it was actually acquired originally as 16 bit) there is absolutely no point in converting an 8 bit file to 16 bit. You gain nothing and risk introducing more problems.

IS THE IMAGE AS PRESENTED HERE EXACTLY AS YOU RECEIVED IT WITHOUT YOU MAKING ADJUSTMENTS OF ANY KIND? i.e. when you opened the file for the first time you saw this banding.EDIT: Sorry I only just noticed that this is the file with your edits - what were they?

You don't need to. Yes, you need to re-open a copy of the RAW to 16, but your precise work such as healing, cloning and small radius masking has to be done again only on the troublesome areas, not the entire image.

You then introduce one file to the other as a smart object, and mask it out.

No need to redo the entire thing.

Convert to 16bit, same conversions, same everything.
Duplicate your global adjustment layers from original 8bit to new 16bit psd (if you get banding, redo your masks, it is possible it's on a mask itself)
Leave local adjustment layers on the 8bit, and turn off the global ones, as you have them in the 16bit file
Drag the 8 bit file into a 16bit file window to get a smart object so that it sits under the flattened conversion.
Put your flattened 16bit conversion(the layer you've gotten with alt+ctrl+shift+e) in a group and mask it out with black, then reveal it for the areas that got messed up in 8 bit.

So you'll end up with a group that contains 16 bit file, and is fully editable, and that you can always expand just by revealing it with a mask, you get all your global masks just like you had before, you preserve all your local adjustments where they have worked in 8 bit, and you get a relatively small file, as you're introducing the 8bit as a smart object in a single layer.

Re: Bad Gradation at shadow area

The banding you are seeing is not in the original image but is being introduced with your editing.

Regardless of the fact that this is an 8 bit image you should be able to modify colour very well to get the desired effect and in this case you have pushed a little too hard with your adjustments and broken the image.

I see no reason why you would need to use 3 different adjustments to accomplish colour modifications and it is likely the cumulative effect of all three is causing the problem. Select one for your global adjustment and you should be good to go
