Simple Frequency Separation

A simple Photoshop action to run a simple Frequency Separation on a 16bit image. It will pause and ask for the blur strength, and I suggest you choose something where colors are visible but barely any texture. If you select a value that is too high, you will see color in places on the "high" layer. Note, the lips are a fine place to see a bit of color, but that is about it. That is how you know you have the proper value. I have this defaulting to 6 pixels, as that works well for most mid-length portraits on my Sony A7riii.
