@nate, been checking every day, and have a tons of negatives on hold to scan - any updates on when 3.1 will be released?

Sorry guys, a couple of things holding up the full launch…
But if you want to try the v3.1 beta you can use these links:
Download v3.1 b7 for Mac
Just run the installer and you should be good to go.
For Windows…
On Windows, download the plugin file from here:
Then to update on to beta on Windows
- Close Lightroom (important)
- Unzip the download
- Delete (or rename and move) the existing NegativeLabPro3.lrplugin file from its location
C: \ Users \ [username] \ AppData \ Roaming \ Adobe \ Lightroom \ Modules \ NegativeLabPro3.lrplugin - Put the unzipped NegativeLabPro3.lrplugin file in that folder where the previous plugin used to be
- Restart Lightroom
- Go to “File > Plugin Manager”. In the “Status” section it should now say v3.1

Does this version v3.1 also adress the “?:0: attempt to index a nil value” error when trying to convert negatives? Haven’t found a solution to it yet, even with all the information from the forum 
Yes. For the majority of users with the Mac Intel issue, this will fix this issue or greatly improve it. I’m still working a few edge cases, but it should be significantly more stable for batch processing.
Also, not yet in this beta, but the final v3.1 works fully natively on Apple Silicon. No Rosetta needed.

@nate unless I’m missing something obvious, I’m not seeing the ‘refined’ option under color process. In fact, I’m not seeing color process in the 3.1 beta at all.
Look in the Advanced tab.
And if you are on Windows, it is a few builds behind and it may be called by a different name… but my guess is you just need to look in the Advanced tab.
Try it on all kinds of conversions, and you may find that sometimes you will see no difference and other times it can be a substantial improvement!
I might be a few builds behind(I am on Windows). I checked all the dropdowns in the advanced tab… or is it called ‘Correction’ on Windows? And multi-pass is the new Color Process? If so, I have tried it and do see subtle(and better) differences on some. It doesn’t appear to be sticky as I have to change the setting on an image by image basis. I’m guessing this is as intended. Would prefer it to be sticky but I can sync the setting across multiple files at least.
Ha, yeah, it’s just a couple of builds behind on Windows. But “multi-pass” here is the new color process.
It’s treated like any other setting, so you can sync it, or set up what you want by default. On new conversions, the new method should be used by default.
It’s a little more processor intense, so with it enabled, you may find it a little slower.
In general, you will see a bigger difference on images where you’ve had to make larger edits in NLP, but there should be subtle improvements almost across all images.

The package for Mac installs a folder with .exe files for windows.
I’ve removed said folder and everything works as expected so far.
Maybe the new installer can do without the ballast?
This is not directly about the beta version but about slide processing in v3.1 generally. Is it the case that NLPv3.1 is NOT intended to recover original colours from badly faded slides? If this is so, can it use a colour-recovered TIFF version of a faded slide (e.g., processed in Photoshop) as the basis for further adjustments in LR (as with negatives)?
NLP v3.1 is amazing for recovering colors from badly faded slides.
There should be no need to preprocess in Photoshop or anywhere else. Just capture RAW and analyze with the Slide option, and it should give you a great starting point.
I should probably point to this feature out more, but my personal collection of slides is quite new, so I don’t have anything I’m able to share. But it is designed to recover colors in this scenario and beta testers have raved about using it with old faded slides.

Very exciting, thanks!
I find NLP great for restoring colours in old slides. I’ve scanned some old Agfa slides from the 60s that my uncle took. They are badly discoloured with magenta and NLP just makes them look natural with little or no effort! Hopefully the new positive option will make this even easier!
It’s a great news! I’ve been waiting for the v3.1 for a very long time!
Nate, could you clarify, please, why I can’t find the Refined Color Process under the Engine Settings Tab? In the Convert tab I see the option of Positive Type. I’m running the Windows version of NLP 3.1.
@nate thank you for posting the beta link and adding the color positive feature. I can confirm that NLP 3.1 beta 7 does such a great job with Ektachrome 100 with very minimal effort. This is such a time saver compared to my previous hand editing workflow for slides.
question for @nate:
I’m using NLP 3.1beta4 on Windows and have noticed the following behavior.
As I understand it, the advanced setting “ColorProcess” (MAC) is called “Correction” under Windows. The options for this setting on the MAC are “Classic” and “Refined,” and on Windows “Single-Pass (fast)” and “Multi-Pass (accurate)”. Is this correct?
When working with the “Classic” or “Single-Pass (fast)” setting, CurvePoints are created/set. CurvePoints are not created with the “Refined” or “Multi-Pass (accurate)” setting. Is this intended, or is it a bug?
Note: The screenshots are in German because I live in Austria.
I’m not speaking for Nate, but I think I have the answer for you: This doesn’t seem like a bug to me, it’s the intended behavior. That’s because in multi-pass mode, NLP only uses the curves for inversion and black and white point setting. The actual color balancing is done in a mask.
Have a look at your masking settings and you will probably find it.

This is great! Loving the beta so far.
One thing to note, and I’m sure you may be aware of it as it’s a beta, but each time I re-open NLP on a photo after the initial conversion it seems to wildly change the conversion. Sometimes the initial conversion will be completely blown out, for example, but upon reopening the conversion will look correct (without changing any setting). Or the conversion will look correct on the initial conversion, but upon reopening the image will now be incredibly dark.
I’ve been getting around it by reconverting each time I want to re-edit an image, as it remembers the settings.
Another thing to note is that Resetting a negative doesn’t forget the last settings, at least for me, and I’m not sure how to completely reset an image as a result.
Edit: Removing NLP from Lightroom, relaunching Lightroom, and then adding it back seems to have fixed both!
