Angry UGH! Freq. separation coming out blurry on texture

am i stupid? my frequency texture workflow is resulting in blurry skin texture.

what are the proper steps to do frequency separation? i think i might be skipping something.

1. 2 layers - high low
2. blur low at around 10ish? (same as you would use in high pass filter)
3. apply bottom image to top image - add, invert, 2, 128
4. set top image to vivid light
5. WTF it's blurry! (i know i can mask the eyes and such, but still... wtf)


i've included the original file and the blurry pos.

actually, your Apply settings are wrong too.

Are you working in 8 or 16 bit?

From Sean Baker in the HPS thread:

1.) Start with two copies of the image to be separated.
* 2.) Working on the bottom copy, run the gaussian blur filter at the intended pixel frequency (same as you would input into the HP filter).
* 3.) Selecting the top copy, choose Apply Image from the Image menu at top (Shift+Ctrl+A on PC; Cmd+Shift+A for Mac).
* 4.) In the Layer dialog, select the bottom layer which you blurred in step 2.
* 5.) In the Blending dialog, choose Subtract.
* 6.) Enter '2' into the Scale box, and '128' for the Offset.
* 7.) Preserve Transparency, Mask, and Invert should not be checked.

* 8.) Choose OK.
* 9.) Your top layer will now look much as a HP result, albeit a bit flatter.* Set the Blend Mode to Linear Light.* Opacity should remain at 100%.
