- Make sure to update your version of Lightroom 6 to the latest version, which is Lightroom 6.14.
- Double-click Prolost Dehaze v1.2.zip to expand it, and open the Prolost Dehaze v1.2 folder.
- Launch Lightroom.
- Open Preferences (on Mac that's Lightroom → Preferences, on Windows it's Edit → Preferences).
- Click on the Presets tab.
- Click Show Lightroom Presets Folder...
- This will locate a folder called Lightroom. Open that to reveal the Develop Presets folder. This is the folder that you'll copy the preset folders into.
- If you have Store presets with this catalog checked, the Develop Presets folder will be in the Lightroom Settings folder that appears when you chose Show Lightroom Presets Folder....
- In the folder you unzipped, open the Presets folder. There, select the three +L 30 Dehaze folders and drag them into the Develop Presets folder.
- If you have Prolost Dehaze 1.0 intstalled, you should remove the +L 30 Dehaze folder from User Presets so that the new +L 30 Dehaze folder can take its place.
- On Windows, you may see an error message about "a problem preventing this folder from being encrypted." It is safe to ignore this error.
- Return to Lightroom and quit the app.
- Now launch Lightroom and go to the Develop module. You should see the +L 30 Dehaze, +L 30 Gradient Dehaze, and +L 30 Radial Dehaze preset folders in your Presets panel.
