Hi Francisco; I have used a number of methods to sharpen in dt .... each one appears to provide a slightly different effect and becomes a matter of what suits the image and our own personal taste. I have used the 'local contrast' extensively with X-trans and find that it is a good addition to the basic sharpening.
