Hi, the issue is likely a profile mismatch… If you were using a camera or scanner that the previous version of NLP didn’t have a matching profile for, and now that profile is available in v3, you can see this happen. The good news is that your conversions are about to get significantly better!
I’ve added more info below in the V3 issues and fixes thread:
"The conversion I made with a previous version are changing appearance when I go the develop module in Lightroom
If you find that your previous conversions are changing appearance WITHOUT even opening Negative Lab Pro, then the issue is that you were previously missing the camera or scanner RAW profile at the time you made the conversion. And now that v3 has added the correct profile, Lightroom is saying “Oh! Here is that profile I was looking for! Let me go ahead and apply it…” But now, there is a mismatch, because the conversion analysis is based on the default Lightroom profile (Adobe Standard), but the “Negative Lab v2.3” profile is now being applied.
You have a couple of options of how to fix this:
Re-converting - Not only will reconverting fix this issue, but I would expect you to get much better results that you previously got when you reconvert (because the correct camera profile is now available). To re-convert, you can do the following: 1) Open the negative(s) in Negative Lab Pro, 2) Go to the “Convert” tab, and select “Reset Photos.” 3) Now hit the “Convert Negatives” button.
This is the option I recommend, but understand that in some circumstances, you may need to just return the appearance of the photos.
Restoring the Original Appearance of earlier conversions - If you’d prefer to restore the original appearance of the negatives, just select the photo in the develop module, and change the camera profile to “Adobe Standard.” You should see it return to it’s appearance before the upgrade. To do this on all your previous conversions in a few minutes do this: 1) In the Library Module, select “All Photographs” from the left pane under the "catalog’ section. 2) Make sure you Library filter is showing (if not, go to “Library > Enable Filters”). 3) Select the “metadata” filter tab, click on one of the filters, then in the lowest section, select “Image Status” as the filter. 4) In that filter, select “Converted.” 5) If you’ve made new conversions in v3, you can filter those out by selecting “NLP Version” in the next filter bar, and selecting just those images made with versions prior to v3. 6) Now that you have all your previous conversions selected, edit the first image to change the profile to Adobe Standard and confirm that it now appears correct. 7) Now select the rest of the images, and select “Sync Settings.” In the popup, make sure that ONLY the “Treatment and Profile” box is selected. After doing this, you should see all your previous conversions return to normal. However, please note that these images cannot be further edited in Negative Lab Pro, because it will attempt to update the profile back to the NLP profile. If you want to edit further in Negative Lab Pro, you could temporarily remove the Negative Lab Pro camera profiles, and the appearance and behavior will go back to before, but this would mean that future conversions will also have this issue and not be taking advantage of the NLP profiles.
