Is it possible, before any corrections are made, have a RAW file sent from Lightroom to CS3 to have a noise filter such as DFine applied and then have the file, still in RAW format returned to Lightroom to proceed with the corrections? I suspect I have to open the RAW file in CS3 as a smartobject, and then run DFine. I'm lost as to how to get it back to Lightroom again though, still in RAW (nef) format.
