I have now completed my new Udemy course for Photoshop:
https://www.udemy.com/color-grading-using-look-up-tables-in-photoshop/
You can enroll for free. It covers:
The basics of using look up table files to create professional color grades for your colour photographs
How to add and make your own look up tables
How to turn colour photos into professional looking black and white photos

The videos are also available on Youtube. To access the LUT files and image resources you will have to enroll on Udemy (It’s totally free!)
