Quite a while back I wrote about a technique to invert your images from negatives to positives or vice versa that involved an Adobe Camera Raw workaround. In looking at my blog stats, I notice that people are still reading that post, so I thought I would provide an easier technique — now that Lightroom 3 has a point curve, you can invert your images directly.
In the Tone Curve panel of the Develop module click on the point curve icon to switch to the point curve:
In the drop-down next to the point curve icon, choose Linear. This will remove all points from the curve:
Now take the point at the top right corner of the curve and pull it all the way down to the bottom of the chart. (It may fight you — it helps to pull it part way, let go, then pull it further.) Then take the bottom left corner point and pull it all the way up:
That’s it! If you accidentally end up with extra points on your curve, click and drag them all the way off the chart, or switch the drop down back to Linear and start over.
If you plan to invert many images, save this tone curve as a preset: click on the + at the top of the Presets panel on the left, give it a name (“Invert”) and check only Tone Curve. Next time you want to invert an image, just click on the Invert preset in your User Presets folder.

If you photograph on negative film and scan it, you may want to invert the image in Lightroom. Or, perhaps you like the “film negative” look, and want to invert your positive digital images. In either case, if you have looked for an “invert” button in Lightroom, you will have found out that there is none.
Martin Evening has a video out on how you can create a Lightroom preset to invert your images. It involves inverting one raw file using Adobe Camera Raw, updating the file in Lightroom to reflect the ACR changes, and then saving these changes as a preset that you can apply to other images in Lightroom. To see the video, click here.
I have gone ahead and created a preset using his method. It works on both color and black and white images. You can download the preset here. After downloading, in the Lightroom Preset Panel within Develop, right-click on User Presets, choose Import, and navigate to the file. The import process will copy the preset to the Presets folder — you can delete the version you downloaded. After the preset is imported, simply select an image, and click on the preset.
Note that adjustments in the Develop panels are still operating on the negative, so they are reversed. For example, sliding the Exposure slider to the right will darken your image rather than brighten it. The same is true with Tone Curve adjustments, and all others.
