Sharpening Technique in Lab mode
Posted: Wed Apr 11, 2007 11:14 pm
Ana lternative technique, especially useful for aechitectural shots, is Lab Mode sharpening.
First convert the image to Lab mode (Image>Mode>Lab Color)
Select the Lightness channel, which contains the black and white image only, and apply quite a high level of sharpening to this, maybe 100 - 150% or more. No sharpening is therefore applied to the colour image and "fuzziness" is avoided.
Then, finally, convert back to RGB (Image>Mode>RGB)
