Sea set ads a blue hue while lowering your contrast and bringing out all the reds. This preset is perfect for sunset photos over water and photoshoots. This is my most used preset.
*Sea Set does not come with the Light Leaks preset. Many of my images with Sea Set have a Light Leak in them.

Just open your new version of Lightroom and open your Preferences folder
 
(Mac: Lightroom> Preferences
 
PC: Edit>Preferences).
 
Choose the Presets Tab from the new window that opens up. Half-way down, click on "Show Lightroom Presets Folder".Unzip the preset into that folder
