How to debanding in C 1 Pro 6.3.3 ?
Hi there 😄 , I'm new to this forum. After silently cruising in for many good ideas on using C1, I still can't find a post about a tool or tutorial on debanding sensor noise per se in NIk software's Define. Am I missing something ? 😊

The Dfine software has the same standard options as Capture One's Noise Reduction tool.
Although they have renamed "Luminance Noise" as "Contrast Noise" the functionality is the same. That software does have some automatic controls as well as the ability to use selective noise reduction (not yet in Capture One) but beyond that seems like straight forward noise reduction.
If you can perhaps elaborate on the problem, what you are trying to fix, the members of the forum may be more apt to assist.0 -
Hi Drew,
from http://www.niksoftware.com/downloads/pd ... rGuide.pdf:Debanding
Also found under the More sub-section, this option reduces banding that may be present in your image. Turn this enhancement on to reduce the color banding structures that may be visible in your images
Which is self-explanatory.
Muddy, Cap One can't do this.
Personally, if I have a banding problem (or more likely, if I'm fixing someone else's files - my Canon 7D has shown visible banding precisely once in 30,000 images), I convert the file to tiff and process it in Photoshop using the debanding function in Topaz DeNoise, which I think is better than DFine - and a damn' sight cheaper.0 -
Color Banding, as defined in the Dfine manual, occurs when Color Noise Reduction is set too high combined with a subject matter that has a large amount of a single hue with varying saturation.
This automatic adjustment in Dfine is likely just an algorithm that keeps the Color Noise Reduction within a certain setting, keeping banding from occurring.
If color banding is occurring in an image in Capture One, you can likely remove it by reducing the Color Noise Reduction.0 -

'Fraid not, Drew - I've seen umpteen examples of it in high ISO Canon 5D Mk II files with no NR whatsoever applied - it's a "Raw level" artifact.0 -

Send me one, lets have a look.0 -
Thanks Keith & Drew

I pulled up three stops(1.5 stops on Background + 1.5 stops on Local adjustment layer) for this heavy underexposure file, what I have are horizontal banding noise on darker area(1st image). I have pulled down 1 stop on problem area on another Local adjustment layer to almost get rid of the banding (2nd image) but still not as clean as I got on Define(demo).

Can you send that RAW file through a support case?
I'll pick it up and take a closer look.0
