How do you invert negative presets in Lightroom?

You can invert negative presets in Lightroom by using the Curves adjustment tool.

Inverting Negative Images with Curves

Here's a step-by-step guide on how to invert a negative image and save the adjustment as a preset:

Open your image in Lightroom.
Locate the "Curves" adjustment tool. You can typically find it in the Develop module's panel on the right.
Manipulate the curve:
- The Curves tool displays a line graph with selectable points.
- Select the lower-left point of the curve.
- Drag this point all the way up to the top of the graph.
- Select the upper-right point of the curve.
- Drag this point all the way down to the bottom of the graph.
This action effectively inverts the tonal values of your image, turning a negative into a positive.
Save the Inversion as a Preset:
- After you have inverted the negative, go to the 'Presets' panel located on the left of your screen.
- Click the (+) symbol to the top right of the panel, and select 'Create Preset'.
- Name your preset (e.g., "Negative Invert").
- Ensure "Curves" is selected in the preset settings, otherwise choose the settings you want to include in the preset.
- Click "Create" to save your new preset.

Now, you can easily apply this "Negative Invert" preset to any negative images you need to process.
