Re: even different ColorNoiseReduction via the XPM files

Hello

PeterPentax posted that the Nikon Z9 XPM setting for the ColorNoiseReduction is +25.

Now I downloaded ISO 6400 RAW files of the K1, K1 II and the Z9, where a ColorNoiseReduction do influence the look of a ISO 6400 RAW file.

The ColorNoiseReduction in the XMP file is for the K1 and K1 II = 0 ....and for the Z9 = +10.

Do you remember all the talk that the K1 II use NR in the RAW file....and now DP use per XMP (= via software) a ColorNoiseReduction view for the Z9 RAW file, but not for the K1, K1 II RAW files, because for them is's set to off (=> it's set to = 0)

BTW: my LR use presets for the sharpness and NR. For example, instead to remove the XPM file, I can also use the reset-button in LR....and than this RAW get viewed with LR's presets (default values) for sharpness and NR . Do ACR has also default values for this, like my LR ? Do use ACR for example a sharpness = 0 as a default value, or a amount of 25 like my LR ?

best regards KPM2

A Nikon user and a Pentax user would follow steps so their camera's images did got NR which was to their taste. DPR shows the defaults, and since different cameras are set up in different ways, and we shoot raw to not get the defaults, one might question the validity of the test.  If one compares Nikon and Pentax models with the same sensor (i.e. the same noise for the same exposure), the noise should be the same - except Pentax applies some pre-save NR in some models. So what would the actual user of each camera set ? DPR ducks the issue by going for the defaults.
