Super easy! In the Tone Curve panel, there’s a small icon in the lower right, click on it. This gives the curve “handles” on top and bottom. Make sure the type is Linear, then click on the lower left handle and drag straight up to the top, making everything white, then the upper right handle down, bringing back the dark tones. Your image is now reversed!

Same as on classic using the curves:

This feature has been requested since ages for dia scanners, but Adobe never provided.
Switching the tone curves does the job but all other sliders become almost useless.

The other sliders still work, backwards! (Antoine you may have more experience in this, I’ve only done it like 5 times).

Indeed, backwards-ish. Highlights are now shadows and everything in between too, but even then, areas are not the same.
not to speak about color, noise, vignetting...
again, it « works », kind of... Adobe could have listened to users’ since request, but they didn’t, as usual. (Which is not related to this topic

Thanks, Antoine, for your expertise! Is there a better way to reverse a photographed negative? Photoshop?

This sounds petty and cheap, but then I'd have to buy Photoshop, correct?

Thank you both. I have NO experience, and a very low frustration level with computers. I was born in the EARLY '50's...black and white tv

@Calors, you can using Photoshop and even automate it. But you’ll lose the non-destructive edits LR provides. And regarding negatives (my bad, diapos don’t need to be inverted! Lol!), the other big drawback is the color editing, as negatives do need color editing!

@Denise, the trick with the curve will do the job if you don’t need any further edits and only have a couple of images to process ;-) you don’t need photoshop at all. That being said, photoshop is now bundled with LR, even though the vast majority would prefer to have LR only. For such an easy job, you mustn’t buy photoshop, that would be a waste of money. Worst case scenario, use The Gimp, an open source and free copy of PS.

@Denise, me too! Uh, the old meaning!

@Antoine, but I’m talking about shooting the negative with my 60MP Sony, then I can “Edit In...” to Photoshop and reverse the image there, it comes back to LR as a TIFF as a positive. If I screw up I’ve still got the RAW negative, and I can learn from my mistakes?

Proud A7R IV owner, are you?
Sure you can!

Check this thread for more info, I'm sure others have more pertinent informations ;-)

All I can say having gone through the same process of digitizing with a macro lens, be extremely carefull with motion and depth of field: you have to be perfectly parallel to the plane, and even then, curvature can ruin sharpness.

Cheers and good luck!
