You are right, for some reason I thought he did. You are right.

However, I was not aware of some of the techniques used to fix skin issues utilizing FS, not related directly to this subject but useful nevertheless.

It is not the same as the normal split frequency. IF you understand the math behind FS, Orig=HF+LF. In a normal FS all 3 channels undergo the Apply Image command. In this LAB version, only the L channel is split that way. The A & B channels are not. In an RGB image there is lots of color on the HF layer, it is not all grayscale. The LAB split is asymmetric from two standpoints: The L is split but the A and B are not; There is a full separation between color and texture.

You can perform a normal FS in LAB by splitting all 3 channels but the results are not the same.

Cheers, Murray
