Sunday night where I live. I am processing some family pictures from this weekend and just discovered a feature that I haven't seen or used before, it's the output sharpening feature in Lightroom. I've only used Lightroom a couple of months so far and still consider myself to be on a steep learning curve. Is this a useful function according to those of you who have used it? Is this a stupid question as I should always use it? Any advice is appreciated.
