Sharpening in LAB Mode

That’s right, the podcast is done…this is part deaux of what will likely be a three part series that speaks to my work flow in LAB mode. The first tutorial dealt with curves and luminance adjustments in the LAB color space, and here, I illustrate how to sharpen in the LAB color space. Great stuff here, and I also briefly touch on producing an action that will create various layered sharpness levels so you can pick and choose which suits your needs best.

Also helpful are some formulas I’ve learned on what works best for various scenarios. I intended to include these in the podcast, but I am trying to cut down on podcast length and keep extraneous info to a minimum. Nevertheless, the various sharpness levels are relevant, so I am including them here:

For people, portraits, etc.: An amount of anywhere from 120-150%, a Radius of 1.o, and a Threshold of 10 works well.

For cities, architecture, etc: An amount ranging from 50-65%, a Radius of 3 and a thresh hold of 2 does great.

For general everyday use: For all others, I try an Amount in the range of 80-85%, a Radius of 1, and a Threshold of 4.

As always, these numbers are not set in stone, and will vary depending on the types of photos you are working with and your particular tastes. Nothing is ever set in stone in a subjective field like photography, so take this information with a grain of salt, and pepper to your own tastes.

Anyway, without further ado, here’s the Sharpening in LAB tutorial! Enjoy! (And feel free to leave a comment or idea – if you do, you’ll be the first!)
