I am feeling smug that I still have some decent computer skills. The last time I updated this Photoshop Action (a kind of macro using Photoshop’s internal scripting language) was a decade ago, for the publication of The Photoshop Darkroom.
The updated Action (Version 01.09.2019) contains some new usability features such as better labeling and hotkey access, and two new LAB color adjustments included in the palette.

My LAB Color Action is free to download for personal use. For detailed instructions regarding creative LAB color and how to best use this action, stay tuned for the new Creative LAB in Photoshop course I am doing for Lynda.com/Linked In Learning.
