In this Natalia Taffarel presentation, she explains that photoshop high-pass filter "skips the edges" of the histogram and that for creating an accurate high-pass filter we have to apply -50 contrast legacy on the image before applying the H-P filter.

I made two copies of the image and apply 10 gaussian blur in the first and in the second I applied -50 contras legacy and then a 10 H-P filter. If what Natalia says is correct, the two layers have to neutralize one another and create the original image again. I set the opacity of the upper layer to 50 and the resulting image lacks a lot of contrast.

Can someone share same inside on the subject?

I'm not sure I understand what you are asking. Is it about the contrast adjustment before doing the high pass trick, and whether or not it's required?

I have tried the technique using just a regular high pass without making any correction to the contrast, and the result is still good. It's a nice technique, and her dodging and burning tips for shaping the light are fabulous. Thanks for sharing!
