Hi There - DxO only gives you the option to "output" the processed file in JPEG, DNG or TIFF Format. So if I want to do additional work on it in Lightroom (other than Keywording etc), It has to be TIFF or DNG - I use TIFF. The original NEF file is untouched and it remains where it was in my HD Folder Structure. Lightroom wont read the .dop file (DxO's "sidecar") so it has to be TIFF with DxO's corrections effectively baked in.

So I'm left with 2 files and 2 sidecar files. The original NEF which hasn't moved, say 49 Mb with its .xmp sidecar file (tiny) and the DxO processed TIFF which is 200Mb (!!!! - yes, that's the issue) with its .dop file (tiny). There isn't a way to save the further processed TIFF file back to NEF Format from Lightroom.

So, unless I have musinderstood the whole process (which is not uncommon for me!) this is the penalty you pay for using DxO and Lightroom together, when you want to futher process DxO output in Lightroom - file size(s). Of course if all you want to do in Lightroom is just metadata based then you can work with JPEG output.

I haven't experimented with DNG yet.

Make sense?
