Except for the one; Custom by Len (that's me) these are all included in the Lumetri Color panel which is
the color grading interface built inside of Premiere Pro. Using the Lumetri Color panel, you can approach color adjustments in a multitude of ways without leaving your current project.
If you Google 'LUTs' you'll find a multitude offered by individuals for free and others; companies for a price.
In Premiere (or maybe other editor packages) Just drag Lumetri to a clip, then in the edit panel, you'll see all of the controls including a pull-down with LUTs which you can step through to choose then tweek to your own vision. I assume that editors other than Premiere / Lumetri have a color panel with the ability to use LUTs.
You can also apply LUTs or do custom color adjustments to footage NOT shot in LOG, but it will have less ability to 'push' the compressed colors.
It's as easy a drag 'n drop a LUT or as complex as a deep dive into the details.
