Originally posted by audiobomber As I understand it, a raw convertor should display NR when the camera settings tell it to, just like it should add the level of saturation, sharpness etc that you dialed into the camera.
No, that's pretty much the opposite of what a RAW convertor should do.
"The RAW file format is digital photography's equivalent of a negative in film photography: it contains untouched, "raw" pixel information straight from the digital camera's sensor."
Tutorials - The RAW File Format
A RAW file should (in theory) be a tabula rasa. It's up to the RAW convertor to make of it what it will, subject to it's own algorithms and the preferences of the guy driving the computer doing the conversion. A RAW processor may take into account the camera settings for NR and WB, and even lens corrections etc, and some software like DCU may let you choose that for your RAW processing, but a RAW processor normally doesn't pay attention to camera settings for such things. It makes up it's own mind.
Originally posted by audiobomber You're saying that a straight conversion in ACR with NR off creates the same jpeg as you get with NR set to High. Could you post a couple of test photos?
No, that's the exact opposite of what I am saying.
I'm saying that a straight conversion in LR seems to apply hardly any NR by default to Kx images it processes, whereas the NR applied to JPG's in-camera can be quite prominent. Therefore Lightroom appears to pay little attention to the in-camera NR settings that apply to SOOC K-x JPGs.
The following pix illustrate this, at the ISO extreme of 12800 where the in-camera NR JPG settings should all be pretty strong, since above ISO 6400 in-camera NR within the K-x is hard-wired in and isn't optional anymore:
Pic 1: The overall scene:
K-x, FA 50 at 1.4, 1/30s and 12800 ISO - LR3.2 conversion.
Pic 2: Detail - DNG LR3.2 @ 100%:
Pic 3: Detail - JPG straight out of camera @ 100%:
It's clear that the SOOC JPG is smudging up stuff in the shadows etc, whereas the LR pic has clearer, more defined grain and less luminance smearing etc.
Both do a fairly good job, though, it has to be said, at this extreme of ISO.
Sorry to crossover for this diversion of his thread
