If you are really looking for LUTs. It means you are an enthusiast video maker or you really wish to learn how to color grade footage. At high production levels: Commercials, Cinema, Short-films, Music Videos. There are no shortcuts to perfect underwater grading.
However, I've built many sets of Presets & LUTs I use on my day to day and I've built packs to help anyone in the amazing route of color grading.
