I went ahead and loaded the trial for LR and PL7 and I’m not having an easy time of it trying to find a workflow that would have me import images in folders into LR, and then use PL7 as my “develop” module. I haven’t had a lot of time to play with it, but I tried using the “Plug-in Extras > Transfer to DxO Photolab 7” option to open an image. I made my edits and then “Export to disk - Export as DNG (all corrections applied)” into the same folder. For something to test, I lowered the exposure a lot, and then changed to tungsten white balance. Once in LR, I had to import the image to get it back in the catalog. Not sure why I thought otherwise. I then opened it in Develop mode and tried to change these two settings back. I was thinking that the DNG would show the two settings changed, but it didn’t. I made an opposite exposure correction and didn’t check in detail but that seemed to reverse it. For white balance, very bizarre because I tried setting the Temp and Tint settings to the same as the original CR3 file and that was way off. So I use the eye dropper and got it back to close and now the CR3 and DNG files look identical but their Temp and Tint are way different. So in summary, unless I’m missing some easy steps, this is probably not worth the hassle just to use LR as a catalog and PL7 as my “develop”. I will definitely keep playing with it for a few days but most likely I’m going to just pick one or the other to go with and not worry about it. If that is PL7, then my old LR will be on my windows machine if I want to go back to them for some reason.
I’m sorry; I didn’t see this post until today, or I would have stepped in and tried to give you more guidance. There isn’t a lot of guidance out there on using PL and LrC together. I realize you’ve figured some of this out by now from your post earlier today.
The material that follows assumes the user has started with one or more image files, preferably Raw, imported into Lightroom Classic, used File > Plug-In Extras > DxO PhotoLab, performed some edits in PhotoLab’s Customize module, and then used in the bottom right the Export to Lightroom button to return DNGs to Lightroom. If instead one uses Lightroom’s Photo > Edit In > DxO Photolab to perform this transfer to PL, TIFF is used instead of DNG. TIFF is a fine editing format that some people prefer, but unlike DNG, it is not a Raw format. Transferring in DNG allows a user to maintain the advantages of Raw formats.
For starters, convergent, you do not have to re-import DxO’s exported DNG back into the LR catalog; it’s already there in the sending folder. What’s very confusing and very annoying to many trying to round-trip images is that when the image comes back from PL, LR opens it displayed in a DxO Collections folder in Library, sorted by date and time of the export, instead of reopening it in the catalog folder from where the image was sent to PL, which I happen to sort by date and time of the original image capture. I believe this annoyance is DxO’s fault, not Adobe’s. IMO there should be an optional setting in PL that blocks this annoying behavior, but there isn’t. There is a script I’ve seen on the web that you can hack into a DxO configuration file that defeats this behavior, but updating PL, typically done monthly, will install a new configuration file that reverts the hack.
So what you get in the habit of doing instead is waiting for all your DNG files exported by PL at one time back to LR to reopen in LR’s Library > Collections > DxO PhotoLab. Ignoring that, scroll up to the original Library catalog folder and select it. Then switch the module to Develop. Your PL DNGs should be adjacent to your CR3s in that folder; if not, you may have applied a Custom Sort in LR. The files may be at the end of the filmstrip; you can drag them back adjacent if you want to maintain the custom sort. You can right-click one or more DxO Collections folders and choose Delete, then confirm. No worries; doing this does not delete the files PL exported back to Lightroom. It just removes the confusing reference to them from the DxO Collections folder. Those folders are likely of no further use to you anyway.
Adjusting color temperature in Lightroom first before going to PL will also confuse things. In fact, before I send a Raw file to PhotoLab as a DNG, I have a LR User Preset that resets ALL changes made in LR. Note that when I run this preset, my LR changes are not erased from the image History in Develop. They’re still listed there, and after the image has returned from PL, I can see again what my Raw file looked like before by clicking one step down below my use of the resetting user preset.
As we’ve discussed before, when you send a DNG this way into PL, your LR changes are not displayed anyway in PL, but I don’t want my LR changes being reapplied to the DNG when it comes back from LR, which is what happens if you send out a DNG with embedded edits PL ignores. I’m going to start over editing the image in LR after it comes back from PL.
So what I do is run my user preset on the file to reset all sliders. (If you are processing a new image with no LR settings previously applied to it–all sliders are default neutral–you can skip this step. But I suggest not skipping it if any LR sliders are non-default.) Use File > Plug-In Extras to send it to PL. In PL I automatically apply a preset I’ve added to PL’s Preset Editor that is specific to the camera body I used. It applies the following settings: Exposure: Vignetting: Correction: Auto with DxO Optics Module, 100. Color: Color Rendering: [set for the specific camera body used]. Detail: DxO Denoising: Deep PRIME or DeepPRIME XD, depending on my ISO and visible noise in the image. Lens Sharpness: 0.99, Details 50, Bokeh 50. Chromatic Aberration: Lateral checked, Intensity 100, Size 4. Geometry: Correction: Auto with DxO Optics Module, Intensity 100. And that’s it. That’s typically all I do in PL. By having a PL import preset for my camera with all these settings, I can in-and-out of PL in seconds. Send them all to PL, then highlight them all, check them all quickly, and Export back to LR. If my exposure was way off, I will get the Histogram in the ballpark in PL using Exposure and/or Smart Lighting, but that’s usually not needed. You can choose to do more. I prefer LR’s and PS’s approach to local adjustments, but since you often prefer PL’s way, if you want to do some local adjustments in PL, go ahead. When finished, highlight all images being sent back to LR. They should all be DNGs. If there are any JPGs or TIFs mixed in, PL will want to send all your images back as JPGs or TIFs. Click the Export to Lightroom button. Set Action to: Export as DNG (all corrections applied). Include: All [metedata options checked].
Now back in LR, navigate back to the sending folder in Develop module. NOW adjust Color Temperature, and make any further refinements you want in Tone controls. You shouldn’t need to adjust Noise Reduction. You shouldn’t need to adjust Sharpness, unless you missed focus. Do any other Local Adjustments last. It’s fast. It works great.
