This preset is worth downloading, even if it has limited use (most times, it will turn a photo in a uniform black rectangle, if applied blindly)
The same website offers some particularly interesting presets for weddings; these instead can be used for several different purposes; mostly, they enhance light areas, some are a bit drastic, some also soften the image, however the result can be quite pleasant. (the photo below was taken in Milan)
A preset should be intended as an answer to the blank page syndrome: "I don't want to spend much time retouching this photo. Gimme something reeeeally cool that just works", or even "I have no idea of how to improve this particular photo: show me some possibilities, and maybe I will find an inspiration"
