Sharpening Technique in Lab mode

Post by John »

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)
