How to add Lightroom Presets to your Lightroom
Two simple methods to add your preset to Adobe Lightroom:
You will have the DNG download(s) from your purchased preset, simply add this to your lightroom images. Once you are on this image, click the top right drop-down menu and select "Create lightroom preset", tick all the selected elements you want to copy (tip: tick all) then name the preset with either the name the creator made or something of your own choosing.
Tip: Name it something memorable to the type of photography is it designed for
You can import presets you purchase or receive from others into Lightroom on your computer with just a few clicks.
Open the Presets panel by clicking the Presets icon at the bottom of the Edit panel. Then click the three-dot icon in the upper-right corner of the Presets panel, and choose Import Presets. Alternatively, you can import presets from the Menu bar by choosing File > Import Profiles & Presets.
In your Finder (MacOS) or Explorer window (Windows), navigate to the preset files that you want to import. Select a single preset or multiple presets. Creators sometimes deliver presets in a ZIP file. You can select and import a ZIP file of presets into Lightroom without unzipping them.
Click the Import button in your Finder or Explorer window. You now see the imported presets in the Presets panel. You can preview how an imported preset will look on an open photo by hovering over the preset, and you can apply the preset to a photo with one click.
Things to Note:
Any preset that you import into Lightroom on a computer automatically syncs to Lightroom on your mobile devices too, so you can apply the same presets to photos no matter where you are.
Adjustments may be needed to all elements to really suit your particular photograph. This includes the radial and graduation filters, which might for example focus on a subject area or vignette. These will need to be adjusted or removed if required.
