Decrease Font Size Increase Font Size Text Size Print This Page

Here is a contrast enhancement technique demonstrated in Better Photoshop Techniques Issue 26 2011

Open an image like this one, taken inside a workshop where the lighting was not adequate to give high contrast.

The image has that typical flatness of a digital photo.

Apply > sharpen >unsharp mask at ~40,250,0 (Choose amount according to image)

Voila, the contrast is immediately improved!
