[photoshop-beginners] Re: Photoshop Sharpening Techniques?

A better way is to duplicate the original file via Image>Duplicate,
then convert the dupe to LAB and sharpen the luminosity channel,
then copy the dupe and paste back into original, and
then blend that back with original via luminosity.
You may then delete the LAB duplicate.
This keeps all the original color information while sharpening the values.
LAB color space is smaller than RGB color space. Converting to LAB reduces color data. Converting LAB back to RGB does not restore the lost data.
God bless you always, all ways,
Paul
