Enhancing Photographic Detail In Photoshop With The High Pass Filter - How To

 This is the same stock photo from Morgue File that I used yesterday.

I tried Abduzeedo's Tutorial for using Photoshop's High Pass Filter to bump up the detail. The background developed some oddness that I removed with the Clone Tool. It's an easy technique with dramatic results.

My Notes:

Open the photo in Photoshop.

Command J to duplicate the layer.
Filter > Other > High Pass. Radius 5 pixels. Blend Mode > Hard Light

Duplicate the High Pass Layer by pressing Command J

Duplicate the Original Photo. Blend Mode > Screen
Use the Eraser Tool to delete the dark areas.

Merge The Layers. Image > Adjustments > Shadow and Highlights.
Shadows > Amount 50, Tonal Width 20, Radius 20.
Highlights > Amount 60, Tonal Width 50, Radius 80.
Adjustments > Color Correction -80, Midtone Contrast +30, Black Clip .01, White Clip .01
