Hello all,
Very quick question regarding order of sharpening and noise reduction. Is NR only supposed to be used to deal with sensor noise (like high ISO noise)? I ask because sharpening obviously introduces noise, which then could be tamed with NR (decreasing sharpness though, right?), but do you really want to do that? Are you supposed to do NR first, then sharpen up and live with the noise introduced therein?
Thanks, and I apologize for the stupid question!
Almost forgot--I do NOT have LR storing metadata in XMP files automatically (the checkbox in the catalog settings), but I noticed that after editing and adding metadata to photos, LR creates XMPs anyway. This confused me, but I checked the folder a little while later and noticed that all the XMPs are gone. Does LR temporarily create the XMPs before its stores in info in the catalog?
Thanks!

The order in which you do things in Lightroom is meaningless...Lightroom processes images in its own order which has nothing to do with the order you set parameters.
And yes, Noise Reduction and Sharpening are really interrelated. It could be argued you shouldn't do one without doing the other. Noise Reduction is off by default but even well exposed low ISO images may need noise reduction to optimize the image when proper sharpening is applied.
