Thanks for that confirmation Nate. The issue I’m having, I think I’m figuring out, is that the images I’m dealing with right now were converted using v2.1. For some reason, the changes I’m making in LR using NLP v2.2 are showing up there but they are not showing up in ACR. And yes, I have LR set up to save to the .xmp file. It seems I have to completely unconvert the file in LR and reprocess. The changes then seem carry over into ACR. Odd.
I also should have added in my original post that I use batch mode in ACR to process my files in Photoshop. I’ll have a folder of images. I then highlight many of them and choose batch mode, that then runs one of my Photoshop actions that does sharpening, noise reduction, output sharpening, and then save to jpeg. So opening from LR is not an option for me.
