LUT or Lookup Table basically means color grading in video editing. This might be the most laziest page ever ha. I know a little video editing enough that I need to use the right tool in a short time. This is one of them.
But what does this means though? Normally you would pick color wheels to match image tone for movie feels, or to match the color you wanted. LUT is like those premades or presets.
You can find those presets on the internet just like those internet lurkers junkies to use.(like me!)
Here are some of those examples on the internet that's clearly how they uses it. (Sarcasm is for my ADHD brain. Thank you!) Normally camera don't have these over-colorful image tho it's just yo brain, and video editing.
