NR suddenly (?) very aggressive

[Nill Toulme]

Suddenly (it seems) the default NR settings that v5.1 (Win) is applying to my 1D Mark IV high ISO (3200 and up) images have become very aggressive — completely wiping out all detail.  I don't know what I've done to make this happen.  It's a huge nuisance.  I've tried clicking the "Reset Defaults" item on the tiny little menu on the Detail tab... but it's already at what the app thinks is the default.  For example, it's applying Color NR at a setting of 55 to an ISO 3200 image, which utterly and completely destroys all detail.

One of the many things I really liked about v5 when I first started using it was the way it did NR at the default settings.  Did I dream that, or have I inadvertently done something to bollix up my "default" NR settings?

It appears that v5's Color NR varies according to the image.

Looking at some base ISO RAWs for my 1Ds2, it jumps around between 42 and 47, and at ISO 1600 goes up to 48.

In contrast, the Luminance NR is constant at 25.

You can obviously manually tweak to taste, but it seems that the "default" is not a constant.

Thanks Paul.  I thought it was something I had done.  Well, in a sense it was... these shots were in a very dark venue, and some were underexposed.  C1 was setting Color NR to as high as 60, which turns the image into a nice watercolor effect.  ;-)
