I have two frames, a stereo pair, and I’d like to match the conversion (ie, I did one NLP conversion that looks good, now I want to do the exact same conversion to the other frame). I see that a Match function exists, as it’s mentioned [here](https://www.negativelabpro.com/guide/batch/). But I can’t get it to work. I have selected the two frames in LR, and opened NLP (3.1.1), but I don’t see a match button/control; please help. ---

…..and then I had a bit of a discussion with @Digitizer which seemed to reach the conclusion that ‘Match’ doesn’t quite do what it says on the tin. > [@Inconsistent with Negative Conversion and Roll Analysis On](https://forums.negativelabpro.com/t/inconsistent-with-negative-conversion-and-roll-analysis-on/9738/3): > > I can understand that of course but isn’t Roll Analysis there so that you can choose the conversion that works best for you and then apply it to similar frames, and by that I mean similar in terms of subject matter and lighting on the day you made the exposures on to film? These frames seem to be just that and if the original exposures varied by half a stop or so I can’t see why that would matter, in the darkroom it wouldn’t make a jot of difference to the filtration needed to print them so tha… However since your stereo pairs are absolutely identical of course I think it would work in your case. ---

Thanks for the replies; I still don’t see how to use it though. If I select 2 photos in LR, and open NLP, I should see a match option somewhere, right? ---

If you have more than one image selected, and the “main” selected image has been converted already, you should see the “match” option appear below the settings. ![CleanShot 2026-02-18 at 16.06.51@2x](https://canada1.discourse-cdn.com/flex029/uploads/negativelabpro/original/2X/0/0cccb4c277e77993eabac2116a281cef09dd2f4a.png) ---

Thanks Nate; I had multiple images selected, but still wasn’t seeing those text buttons under the settings popup. ---

I meant I wasn’t seeing them before, since you sent the screenshot I am seeing them. Thanks for your help.
