Since 7.x came out, I kept feeling that there was something strange in the Noise reduction advanced setup and I finally realized the whole issue today.

In 7 there is a Noise reduction advanced tab.   If you open a Phase One raw file, you will have 2 sub tabs, "surface" and "fine grain".  If you open any other raw file, from any other camera,
this changes to "detail" and "fine grain" example, Sony, Nikon, Canon etc.

When you open any raw file from any camera, the default is at 50.  So, 50 for Surface if Phase file and 50 for detail if any other camera (Nikon, Sony, etc)

I have long stated that 50 for a Phase One file is too much and tend to back down from 50 to around 10 or 5.  You will see a big increase in overall details especially fine ones.   I was using this same logic
35mm DSLR camera files, and that is a mistake.  Here the tab is "detail" and you want to leave it at 50 or go stronger.  If you move the slider to the left, the fine details will become less noticeable and if you move
to the right from 50 they get stronger, but you will see a bit more noise. 

With a phase one raw file and the, "surface" slider,  if you move to the right from 50 you get an even stronger REDUCTION in detail and if you move to the left you get an INCREASE in fine details. 
With a Non Phase one raw file and the "details" slider, if you move to the right from 50 you get and even stronger INCREASE in detail and if you move to the left you get a REDUCTION  in fine details.

My point being that the two settings, "detail" and surface" work exactly opposite if you move the sliders the same which is easy to do if you are moving between camera types. j

Not a bug, but a strange design and one that can make a big difference in final sharpened output.

Hi Paul,

You will only see the Surface slider if you are running the V6 processing engine.

Thanks for the clarification.  I was going between several machines and missed the Vr6 engine was being used.  As you point out, once you make sure you are using the Vr7 engine, the detail slider works fine.  The higher you slide it to the right the more fine details are shown. 

Thanks

Yep!  Its easier to understand as well.  More details - higher number!
